Thanks for the feedback and appreciate your views. Here are my thoughts on the issue: Our engg's and operators say that Samsung is the easiest machine to train new operatos on. They however love Universal and Mydata and are pretty open to getting an

Assuming you are working to IPC standards, are you working to Class2 or Class 3? Class 2 has an exception to the 75% barrel fill (para 6.3.1, page 6-7). "As an exception to fill requirements of Table 6-2 on PTHs with thermal planes or conductor

Do any of you guys have a list of parts that cannot survive hanging upside down during reflow soldering. As our board designs become increasingly dense and higher speed, we need to use all available pcb real estate. This means locating parts we hi

Bman Each area and process has a unique machine for a reason. Professional engineers at the various OEM�s have thought these things through and there are specific reasons why you don't wash stencils in a board washer, bake pizzas in your reflow ove

Help Please! A friend of mine works for this company (a novice in the hardware world), they are thinking about covering their PCBAs with Epoxy (don't know what) so to prevent hackers from damaging their PCBAs - they claim it is costing them too much

It was a nice discussion. What I did here was a thermal shock test 1 hour@ +90 deg.c and immediately 1 hour @ -40 deg.c. The second test I did was a high humudity test for a week. After each test, I carried out a peel test with scotch tape. Those bo

I would discourage the use of city water at all - where rinsing electronic parts is concerned, it contains too much contamination. If practical, route DI water to your first tank and implement some aggitation (either nitrogen bubbles from the bottom
