hello, can anybody help to compare SAM to x-ray methods with regard to inspection of semiconductor devices (smd LEDs, for instance)? Advantages and disadvantages of each method? Thank you!

We are a relatively small company looking for a good smd counter. Would appreciate any input from people using motorized versions. Thank you Linda

Sorry folks. I'm just a naysayer here. Let's look at this BGA thing...... We've all been successfully processing down to 16 mil FP stuff for years, now--some of us down to 11 mil. Once the printing process was stabilized, paste rheologies were matur

Assuming that you are talking about voids in solder connections: * Consider voids on the surface of your solder connection a defect. * Consider voids that you can't see to be a process indicator. See A-610C, 12.4.8 for authoritative guidance.

I hope to get some feedback here. I have a SMD connector that reflow-solders quite poorly (I guess solder paste or profile issue). On the X-ray I see strange bubbles, does it mean there are voids under pin? Generally I am not satisfied with the sol

Does anybody know where I can get a SMD digital reel counter? I am looking for used; is there somebody that sells used, refurbished?

Does anyone have experience with this Manncorp component counter? Seems to be great value for the money and has great features. How well does it stand up to long term daily usage?
