I figure using Lunix is about the only way to avoid MS "Error 400" and the "blue screen of death". That would be great to have some IE migratory assistance. Is it tough to do that trick? Did you know that we don't have an IT department? So then,

10% on various BGA packages. I checked the profile and we are getting "ideal" reflow conditions (~ 60 sec. T.A.L.). Ramp rates, temperature deltas before spike zone, and cooling rates are ideal too. I don't believe it's a profile, print, or paste

Pete, I'm wondering how much optimisation you needed (or were allowed) to do with respect to connector design. The first one we evaluated had a row of leads that I can only describe as "crescent" shaped in cross section. Impossible to get even 50%

The size of a feeder is determined by the width of the carrier tape the components come in. i.e. If you measure the width of the tape with a precision ruler or calipers that measurement will be the feeder size. Also, when you order parts the tape siz

I know this subject has been beat to death, but I need a clarification. I keep getting mixed messages about how much gold is required on a PCB for a reliable solder joint. Some people are saying 3 - 5 microns, some are saying 3 - 5 micro inches. Do a

Fellas, Here's the deal. We're getting shorts on a limited number of boards under the BGAs; about 1 out of 6 boards. The thing is that these boards have about 10 BGAs on them. On the one out of six boards with shorts, the shorts are everywhere and

You should evaluate products from Datapaq, Electronic Controls Design, and Kic Thermal Profiling. Each sells very good reflow profiling equipment. Beyond the straight forward issues surrounding the question of "Does this thing produce a good profi

I used a Blue M batch oven quite a bit to cure in works great. All you have to do is get the board up to cure temperature, 150C normally and your all set. It will probably be in there longer than the time required but at that low temperature it shoul

Dek 265 Get yourself Formflex tooling for quick changeover time. The principle being tooling pins are raised by a combination of pneumatic's and hydraulics to meet the underside of the pcb which rises to print height. No longer will u have to judge

You guys are absolutely correct, and i thank you for your invaluable advice. I would like to know if there is any online manuals for the equipment i stated b4. I have tried so hard to find these with little results. However i did get onto th
