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.

Device Re-Tinning

New BEST Logo
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.

New BEST Logo 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!

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.
