2007 2nd Half Training Schedule Released

BEST delivers training in printed circuit board assembly, rework and acceptability criteria along with classes in cable &wire harness assembly throughout the year.

Our newest course schedule for the 2nd half of the year including the newest IPCJST-001DS Space Addendum certification is now available. In addition check out the schedule for soon to be released PCB electronics assembly course schedule. This class will focus on the assembly of PCBs from board fab all the way through test.

If you would to learn reserve a space in one of these classes or have further questions place a call Katy Radcliff at BEST at (847)797-9250 or email This email address is being protected from spambots. You need JavaScript enabled to view it..

 
Prototyping Services

Let BEST be your assembly source for prototype PCBs. The same quality of work that we have been performing in reworking your critical PCBs quickly can be expected for your critical first product builds. Whether you supply the parts or we do, our certified soldering technicians can turn out a quality product. We can handle the prototype (5-30 pieces) or larger quantity more difficult or critical hand assembly assembly projects.

There are several compelling reasons to chose BEST for your prototype development, small run OEM or development builds. These reasons are BEST summarized below:
* We understand the needs of small business-because we are a professionally-run small business
* We understand speed because of our experience in the rework and repair of printed circuit boards where turnaround time is essential
* We have experience in quickly building lead-free assemblies for initial evaluation of new components, board finishes and materials
* Our business model is based on BEST delivering prototype and small quantity electronic assemblies to you and your organization and NOT on building thousands upon thousands of the same assemblies

Use our convenient PCB prototype assembly estimator here: or ask to speak to Laura Ripoli at (847) 797-9250.

 
StencilQuick(TM) for Prototype BGA Placements

StencilQuik(TM) allows you to place BGAs by hand for prototype developers. Once the alignment of the StencilQuick(TM) has been accomplished over the pad areas and solder paste has been squeegeed into the apertures technicians can "feel" the device fit into the apertures. Due to its stay in place nature which allows you to use solder paste of a greater volume to success rate of your BGA placement is in the 95% or greater first pass yield realm. Since you can do it yourself you can control your own destiny in terms of timing on the project.

These flexible solder paste stencils remain in place on the site location becoming an integral part of the PCB assembly. StencilQuik(TM) is manufactured from a polyimide film with a high temperature adhesive covered with a release liner. It is the same type of material you have been using with bar code labels and for protecting gold fingers during the wave soldering process. These stencils are laser cut from high quality, anti-static polyimide film with a residue-free high temperature adhesive backing. The StencilQuik(TM) apertures correspond to the land patterns on the PCB and define those portions of the PCB which are to have paste or paste flux applied.

We either have made your pattern already or can design one (no tooling charges) and ship it to you in 5 business days or less. Call us today at (847) 797-9250 to see how we can be of service!

 
Resistance Soldering

drink charm Resistance soldering allows you to solder faster. A resistance tool uses two probes. These probes pass a current through the material being soldered. The probes and the solder heat up very quickly because of their resistance to the current passing through them. Removing the solder breaks the circuit, and the tips cool off quickly. In some marketing materials these systems are also known as "cold heat" soldering systems.

There are three key components of resistance soldering: 1. A specialized step-down transformer that will generate the appropriate current 2. A resistive material to generate the heat 3. The ability to complete an electrical circuit

There are some advantages of resistance soldering tools that we BEST have found advantageous on specialized projects including where: 1. Heating is instantaneous required and confined to solder connection. Larger solder cups or components being soldered or removed that are in close proximity to heat sensitive components are a few examples. 2. Speed is required. Resistance soldering is many times faster than soldering with traditional irons. 10. Boards act as "heat sinks" and bottomside heating is not possible or desirable.
