Hi, This Not so easy as one wuold think. Has the thermal pad of yours vias? How many? What's the via's dia? What is the pcb thickness? If the the pcb has a "ground layer" connected (vias) to the pcb thermal pad, it could sometimes be a little bit tri

Thanks, Chunks. Your first post was correct, it turned out to be the battery. That is that problem solved. Unfortunately I have now got an error message saying Flux Management Failure. Is this just a coincidence? It sounds like something to do with t

WE are experiencing a faster than usual deterioration of solder tips. We have been conducting a cost study of our current irons/tips and are trying to decide whether to upgrade the irons or not. Is anyone else experiencing this problem (could the c

I've worked with Juki and Panasonic/Create. Both have been good machines, but we've found Juki to be superior in cost, performance, and service. Our 750's are 8 years old and still run great. We've just gotten a 2060R this last year, and we've rea

Personally I wouldn't care what the industry standard is....if I was producing something where 15 out of 100 failed, it would not be acceptable. Determine why this is happening and fix the problem and don't be concerned with what anyone/everyone el

I'm a new guy in this field. I have a question about solder paste process. Is there any effect to the solderbility if we do a lot of contact to copper pad without using any insulation ( direct to the finger ). Where can i get information about smt pr

For chip components it is very hard to identify specially the capacitors. You could get sample of each chip manufacture and compare the color. This is very labor intensive task. I suggest to sort by value ( capacitance, resistance) than by manufac

Because of some mechanical issues we believe that we need to counterbore 2 holes on one of our 2.4mm pcbs. We want to counterbore to a 0.5mm depth. The unplated hole is 4mm diameter and the counterbore diameter is 7.5mm. We have never done this befor

it's a vacuum dewar so adhesives will eventually permeate and the vacuum would be lost. Sounds to me since I have the N2 capability, I definately should try it. I am obtaining Indium Flux and Solvent so I can adjust the activity when I start using
