Yes, I ordered this stencil, I checked the "cut" file vs the gerber before the stencil was made, and it matches. Attached is an overlap of the stencil over the original gerber. Regards

Because I guess for almost years nobody else even came close to having an overlapping sales pitch. However, today, most brands have a "flex" placer, feeders that can take strips of tape and software options that help in some way with running smaller

What a challenge! I think it all depends on the equipment used. Seems rereflow of BGA isn�t that good (see the advices for wavesoldering BGA populated boards). Although you might check for the tacking force by sending a sample BGA board head over thr

Hi Jerry- The belt splice kit we used were made by Eagle Belting Company (Now Fenner). You are correct in the splice process...one other thing we did was trim the extra "roll Back" or flash of melted material. I prefer the Mini or regular but splic

Can someone recommend a company that will X-Ray my boards and provide some analysis of the results ?? I just got a lot of assembled boards back with a large number of bad boards (after several sucessful runs by this assembly house) I am trying to f

We have run some experiments on double side BGA assembly. Our preliminary results show that complete overlap of top and bottom BGA's indicate fair results, even after reliabiltiy tests (vibrations, temperature cycles, HALT). I will be interested to h

We have a C-740. I agree with the second pass statement. Be careful how much you overlap. Also make sure the board is very clean before you coat or its worthless. You will be able to get very accurate results without masking. Let me know if you need

The top picture probably won't run. You have black soldermask dramatically misregistered and overlapping what look a lot like fids. Either your machines are going to pitch a fit and not find the fid or they're going to center on the soldermask outlin

It's a terrible idea. Through holes should be drilled in the exact center of a pad +/-. Have the two holes go out back and settle this. Whichever hole returns, that hole get to keep the pad. The other hole needs to get its own pad. End of story. Th
