 |
The Palatine Township Apple Tree Campaign, collects and distributes new backpacks and
school supplies to economically disadvantaged children who live in Palatine
Township. The program is designed to provide students, who have been referred
by local social workers, with all of the supplies required so that they can
start school prepared and ready to learn. In 2008, 1,200 students were
recipients in the annual program. Drop off any donations at BEST.

Dear Subscriber;
|
For those of you doing military builds I have included a discussion on device retinning.
If you are near the Detroit or Northern Ohio
areas we invite you to either our IPC A-610D CIS training class
to become certified or our technical discussion on the "nuiances
of IPC A-610D".
For those of you interested in teaching on the subject of electrostatics and field theory I have included a cool DIY Van De Graaf generator build instructions.
I also invite you to eee our latest StencilMate (TM) leadless device rework video here.
My
son and I were able to fire up our lighters recently.Once for fireworks
and once for "Freebird" as part of the encore invitation during a
recent Lynyrd Skynyrd concert.
Best wishes for a fun summer,
Bob Wettermann
President, BEST Inc

Device Re-Tinning
BEST Inc
has the ability to provide high quality, device retinning services.
Tinning of components is used amongst other things to change the lead
finish of components from lead-free to tin lead. In addition, it is
used to mitigate tin whisker growth, which can form when pure tin
plating is used. Hot solder dipping of pure tin-finished terminations
using tin-lead (Sn-Pb) solder reduces tin whisker formation by
replacing tin with a tin-lead alloy. It can also be used to improve or
restore the solderability of the parts, acting as the primary finish
for the terminations. Lead Tinning can also be used in the restoration
of corroded components to their original condition.
In addition to lead tinning services, BEST can
return the parts in either a tape and reel format or in
customer-supplied matrix trays. Optical inspection services and part
marking can also be performed on the retinned components.

| IPC A610 CIS Certification Training Comes to Michigan |
BEST is bringing its training offering on the road at the end of the summer.
Students will be instructed on:
Terms and Definitions
Handling Electronic Assemblies
Mechanical Assemblies
Component Installation Location/Orientation
Soldering
Cleanliness
Marking and Coatings
Laminate Conditions
Discrete Wiring Assembly
Surface Mount Assemblies
Worker proficiency students will be evaluated on their mastery of
the IPC-A-610D material through end-of-course tests that have both
open-book and closed-book components. Students must receive an average
of at least 70% on both tests. Upon satisfactory completion of the
course, participants will receive an IPC certification that is valid
for 24 months .
 : Cost: $275 per student (handbook extra)
Location: Holiday Inn Township, MI
Call (847) 797-9250 to register as the class size is limited!

 Making Your Own Van De Graaf Generator
While this does not have the power of the one in your science museum electrostatic principles can be learned!
Materials:
Plastic tupperware (microwave safe)
Wires, 20 gauge black and red
A nail
A small d.c motor (I got mine from a small hand-held fan)
A piece of PVC pipe (Mine is 3.8 cm in diameter for working/finger comfort)
A thick rubber band (NOT black, it may be conductive)
A wooden skewer (satay stick)
A plastic bag
A roll of tape
A soft drink can
A mineral water bottle
(2) 3volt batteries
You can get sparks a few mm long from this design. Pathetic
compared to the sparks you can get by sticking a piece of aluminum foil
to a TV screen. But Van de Graafs are not just used to create high
voltage. They demonstrate many different principles in electrostatics
that you can learn while playing with it. Complete plans and construction here. | |
