Larry, Yes, no matter how much you�d like to avoid using NC, you probably will have to start using the stuff, if the design [sales, in your case] types have their way. We can clean WS under 1mm and 1.25mm pitch BGA. For 0.8mm pitch BGA, we use NC.

I would like to know the Stated Specification for PTH size tolerances. Or is there a generalised acceptable limit?. We have some PCB's with hole sizes that I consider to be way off what I would deem acceptable, ie Finished hole size should be 0.89mm

Hi! One technique: 1. Remove all balls 2.Make > a mask(stensil)for reballing.The holes of the > mask must be 0.8-0.9 the size of the pads. 3. > Reball chips 4. Reflow chips Good luck Hi Yes,we have done quite a bit of reballing of BGAs with

In reviewing the JEDEC 95 guidelines (2002) there is not a mention of tolerances that have been agreed upon for today's finer pitch devices. There was no mention of the solder diameter tolerances (low melt temp) allowed for 0.8mm, 0.6mm and 0.5mm pit

Hi all, Need advice how to fix RJ45 short issue after wave solder m/c .Few actions taken to resolve this issue but the outcome was inclusive which was 1. Modify wave pallet 2. Change conveyor setting from 0.8meter/minute to 0.7 meter/minute 3. Clear

we have some problems in soldering joints such as insufficient solder and misalignment on some RC0402 and CC0402,i don't have a pic here. our SMT enginner doubts the PCB land pattern is at the fault.here is what we measured results.pad length:0.9mm,

Dr. Lee, For lead-free wave soldering, we are recommended to use SnCu0.7, why not 0.8 or more ?? Since SnCu0.7 has eutectic melting point at 227 deg C, does it mean with more Cu or less Cu, the melting point will be higher ?? Also, in lead solderin
