Excess Inventory Management
In today’s highly competitive marketplace it is vital that every resource a company spends is focused on its most current products and core competencies. ESCS recognizes that need and offers several programs to address our customer’s excess inventory. ESCS will tailor a program to meet your corporation’s unique goals. Your needs and objectives are discussed to provide you the opportunity to increase your operational efficiencies and reduce your expenses thru the outsourcing of your excess inventory.
ESCS offers the needed funding to free up product that has the proper traceability that can be resold to our customers without additional testing.
Product that does not meet our quality requirements shall be handled separately and sold off as scrap to another approved source.

Quick Cash Purchase
If you need to recover inventory costs immediately, ESCS will pay cash for your inventory. We can quickly provide a bid to purchase your excess and eliminate future inventory carrying costs. Simply provide a list of saleable parts you have traceability for and ESCS will make a cash offer. If you do not have the proper paper work, just give us a call and tell us what you have to sell. Once the offer is accepted, we shall instruct you where to ship the inventory. Upon inspection and proper receipt of described inventory
ESCS shall pay net 30 days the agreed amount less any discrepancies discovered during receipt of goods.

Consignment Exclusive
When utilizing the consignment program the seller gives ESCS the exclusive right to market and sell their excess inventory (included on spreadsheet with all relevant c of c details). ESCS shall sell the product and ask that the stock be transferred to our shipping location within 3 business days. The product is then counted and inspected per ESCS standards. Upon acceptance by ESCS and shipment of product to the customer, ESCS will provide an end of month audited accounting of the inventory sold that calendar month. When you participate in this program your parts are sold only by ESCS. We then split the revenue with you which may result in
a return of more than what you paid for it! $$$$$$$$

Procurement Services

End-Of-Life Inventory Management

With our extensive network of industry partners, we can discreetly move products to alternate channels while reducing inventories, increasing liquidity, and maximizing the value of obsolete stock. ESCS will negotiate directly with the manufacturers for last time buys, and design a schedule that will minimize the impact of taking the entire product at one time.

Engineering Services - Free
Whether the project involves a new design, a complete re-design, or a migration from obsolete components, our sales team is well versed in reading and understanding the requirements of a specified drawing. ESCS can work with your staff to provide you a comprehensive solution to a broad range of manufacturers and technologies.

Part Number Management
ESCS maintains a database that provides us with an effective management of internal and external part numbering schemes. Our staff can often identify if a company has assigned multiple internal numbers to the same manufacturers part number saving you money on excess inventory. Military parts with dual part marking are also identified.

Kitting of Connectors
Our kitting capability ensures our customers receive the components they need rather than the large minimums demanded by some of the large distributors. Product is delivered in a bag & tag method with the internal P/N, cage code, and quantity of the various components required for each of the kitted components. In our complete pre-counted packages our customers enjoy the following benefits: reduces inventory, minimizes storage space, and reduces ordering complexity which saves money. visit http://www.electronicsupplychainsolutions.com/connectors.htm
ESCS approved suppliers can fabricate connectors to your drawing or to a milspec.
We can deliver some D38999 connectors in just 7 days.
Let ESCS schedule your annual connector needs today.
We buy ahead to allow for those unscheduled pull-ins.

Product Preparation

Device Deprogramming & Testing
ESCS provides third party services of deprogramming product to ensure the blank product shall accept the new required programming. These testing capabilities allow clients to enjoy the highest level of component quality.

Bar Coding
Bar coding is contained in our product identification, which reduces cycle time and facilities automated routing. ESCS has the systems in place that supports all industry-standard bar code symbologies and formats; however, we are not utilizing its total capabilities at this time.

Dry Packing
ESCS uses an outside service to dry pack our product when requested. This process can lengthen shelf life by reducing the likelihood of moisture damage to components. As a service to our customers we may sell less than a full minimum. In this case we would send out the requested quantity for dry packing as well as the remaining inventory. MSL level III packaging is also available upon request. ESCS does not, as part of its quality management system, perform these services or maintain any nitrogen on site.

Lead Forming & Tinning
ESCS currently out sources lead forming for many prime contractors’ drawings. ESCS staff will work with your engineers to ensure the forming called out on your drawing is acknowledged by our supplier, and all foot prints and coplanary issues are agreed to prior to performance of any work. To ensure product older than two years accepts solder, ESCS recommends and outsources it’s tinning. This gives our customers the assurance that all products will accept solder, and not slow down production.

Tape & Reeling
ESCS works with customers to improve their manufacturing efficiency. Our approved third party tape and reel capability allows us to provide specific components on a reel for direct introduction to our customers' manufacturing process. Whether you are looking to meet your standard costs or react to a crisis, we offer both a value offering as well as a short run or express service.

ESCS Electronic Supply Chain Solutions has got your back.



ESCS Quality Statement & Certifications

ESCS Electronic Supply Chain Solutions was one of the first in our industry to be certified to AS9120 and holds the highest quality standards to date.
ISO 9001:2000 & AS9120:2002 in accordance with the requirements of AS9104 issued by NQA National Quality Assurance USA and ia ANAB accredited. NQA also certified NASA

Our quality assurance process begins with procurement, which includes an approved vendor data base and continuous measurement of vendor performance (on-time & quality). A matrix is kept of these ratings. Companies that maintain a perfect on-time and quality rating with out any SCARS are presented with an annual certificate of acknowledgement. ESCS cannot absolutely guarantee against counterfeit product, however the Electronic Supply Chain Solutions AS9120 certified quality management system has proven very successful in achieving a near-zero defect rating. Products and packaging undergo both a visual incoming inspection and a comparison to manufacturer specifications. Product that is purchased directly from the manufacturer and / or its franchised distributor are demanded to be broken down by separate lot and date code. AS9120 demands split lot traceability which ESCS is to keep on file for 7 years. Product that does not have the proper pedigree paperwork is sent out to a third party test house for a functional or internal visual test. Products with date codes older than 2 years are often tinned as to ensure solderability. ESCS ships only products that completely adhere to all of our customer supplemental purchase order conditions. ESCS flows these conditions to our suppliers to ensure the product ordered is what is and delivered on-time!
Both an AS9120: 2002 & ISO 9001:2000 certification means we are looking out for you!
Achieving ISO 9001:2000 has been done by many companies in the past ten years but only a handful of distributors have under taken the extra 100 requirements that were deemed to be necessary to the aerospace industry. This goes beyond being dedicated to the adherence of every quality and performance standard created by the International Standards Organization (ISO). Our commitment to the highest quality through constant measurement and improvement of our processes is unsurpassed, and has resulted in exceeding our customer’s expectations.

ESCS is scheduled for its 4th annual AS9120 audit and is a quality advocate. The http://www.electronicsupplychainsolutions.com/qindex.htm website is packed with information both customers and suppliers can use to “Combat Counterfeits” and protect themselves while they pursue an aerospace quality management system.

DO YOU REALLY KNOW WHO YOU ARE BUYING FROM?

YOU SHOULD KNOW WHO YOU ARE BUYING FROM

Many independent distributors subscribe to putting their website graphic user interface over a broker search engine that lists its members around the world inventory. While the whole world’s real or available inventory shows up as available from your supplier, the truth is that your professional sales person has visibility to what is real and most suppliers that post inventory on their websites usually don’t have any inventory at all.

At ESCS we believe that by giving our customers the information they need they can make sound business decisions. After our investigation we provide the market conditions and offer the best product from our approved suppliers ensuring we make a timely delivery of a product you can trust. Where does that cheap product come from?
China, India, Iraq, Mexico, etc. Broker stock from a rusty bucket is cheap as well.

As a member of the Coalition against Counterfeiting we can tell you first hand that counterfeit products are costing the US 750 BILLION dollars per year. Visit http://www.combatcounterfeits.com/ to learn ten steps you can take right now to protect your company. Ask to join the Electronic Supply Chain Solutions mailing list to be kept informed.

“Someone's excess inventory scheduled for scrap is usually rescued by a profiteer.” $$$$$$
Buy from a supplier who knows where the product came from and has the paperwork to prove it. If you have ever felt the ramification of buying substandard product and can remember all the facets of your business it affected, Deja Vu is a bad word!

Disappearing Solder with a Lead-Free Process





Electronic Supply Chain Solutions shares valuable information from Bob Willis on…
Disappearing Solder with a Lead-Free Process

Question? “Have you ever wondered why you see changing volumes in your lead-free solder joints?” Although lead-free materials do have a different density they are actually talking about the loss of solder to the component terminations during reflow. During lead-free introductions it is common, but not ideal, to use tin-lead coated component termination either because nothing else is available or they have been supplied without warning. Using tin/lead terminations with a lead-free paste has been shown, in some studies, to have an impact on joint reliability and also cause secondary reflow on wave soldering resulting in lifted leads. With a lead-free process solder paste is printed on to the surface of the pads, most commonly 0.006” of paste is used. Ideally one of the alternative lead-free printed board finishes like gold, tin, silver or copper OSP is specified. Lead-free solder leveled alternative like tin/copper/nickel may also be considered to replace tin/lead and is by far the most solder able coating depending of course on thickness. Component terminations are then automatically placed into the surface of the paste; the board then passes for reflow in the normal way. During reflow the board passes through convection or vapor phase soldering (VPS) process reaching and exceeding a normal reflow temperature of 210-220°C used for tin/lead assembly. In this situation if the component terminations are tin/lead plated or dipped they will move into a liquid state and are very wettable, probably more so than most alternative PCB finishes and the alternative component termination plating like tin and palladium.
Example of tin/lead “Wicking” This resulted in an open intermittent joint.
When the lead-free solder paste reaches reflow temperature at 217-220°C the solder is far more likely to wet to the component termination particularly on leaded parts like SOIC, QFP or PLCC. The board assembly will continue to rise to 235-245°C and hold until all the terminations are above reflow for a minimum of 30 seconds. In the case of parts with leads there is a large surface area to wet. The result is “Wicking” a process defect that can occur during normal tin/lead processes when the solder ability of the PCB is poor and the component very solder able. In the past it was very likely to occur with convection and IR ovens with mainly top heating and limited bottom heating. It could also occur with mesh belt systems as the belt could hold the board temperature down allowing the component termination temperature to rise much faster. VPS originally exhibited this type of defect more commonly on batch vapor phase systems with no or poor preheat. In this case the lead terminations would reach soldering temperature much more quickly than the printed board.


Example of tin/lead paste “Wicking” on copper OSP board finish after reflow. This was due to incorrect PCB cleaning which stripped the OSP surface protecting from the pads.


Examples of “Wicking” on gold pads on a pocket pager application with tin/lead paste when the solder ability of the pads was poor.


Example of a satisfactory lead-free joint but the increased volume of solder can be seen on the surface of the tin/lead pin away from the joint area.
In the case of lead-free reflow with tin/lead component terminations the wicking process is practically the same. However, it can result in the reported disappearing solder contributing to the component coating and not joint formation. Although many people will not have seen this type of defect before it has been encountered and fairly well understood. It’s the lead-free aspect that may catch people out during manufacture and final inspection.
