GEB - We have a 1.0 mil camera for GSM1 that we do not use. We would prefer to have a 2.6 mil on our machine. Are you interested in a trade?

Interesting... where are you based? I am in the UK. What types of components benefit from having a 2.6mil over a 1mil?

We are running an older GSM1 machine (sw.runs on OS/2) and I would appreciate any hints which vision algorithm to use for best results with QFN and similar parts. One of the ULC's is 2.6mil/pixel. - Dejan

We run a bunch of .5mm qfn on a GSM1 with a 2.6mil camera, from 16 pad to 100 pad. Works like a charm. We call them a PLCC.

That's one of the old IPC-A-610 revs. The latest, Rev D removed the size allowables and put in a general criteria statement(section 5.2.6.1).

Can someone clarify whether IPC-TM-650 Test Method 2.6.27 (Thermal Stress, Convection Reflow Assembly Simultation) is required for all bare board fabricators? Or is this test method optional, depending on the type or class of boards being fabricated

We run these all the time. Agree with other posts. I tried a few times to read leads on these with mixed results. Leadless is best. On GSM - run as leadless or chip and crank the lighting up on 2.6 or 4.0 ULC. You should get good centering.

IPC-A-610E-2010, Acceptability of Electronic Assemblies, 8.3.4 Castellated Terminations talks to the acceptability of solder connections on components like yours. It’s tough to say from the pictures, but I’d say your issues are: Missing solder: Plat

Hello I am looking for a best solution to make a prototype of Single sided and double sided board. Using Orcad. The line / track width are 8/8 mil. the hole sizes are 0.6 0.8 , 1.2 and 2.6 mm. The size will be approx. 175 x 130mm. Could you please

Because most placement machine mfgs' feeders vary in width sizes its best to get the reference from them. Like how many 8mm slots does their 16mm consume, and so forth. Std. Sizes I've seen are: 8mm, 12mm, 16mm, 24mm, 32mm, 44mm, 56mm, 72mm, 88mm, 10
