EMS-Engineer, Lead free alloys have a very low wetting creep. You probably will not ever get the same type of weting with a LF as opposed to SN 63/37. The question is if it is acceptable. Lead free solder joints cannot be inspected to the same crite

Your problem is easy. Lead free solder is like 63/37 solder paste when it was started. We make things complicated. We believed before that lead free has high melting temp and will not produce good fellet so on.... The only thing you must do is to lo

Hi Rob, I don't think you're so right about this thing. In China, there're so many companies that are using the most advanced equipments in the world. Machines using in Europe can also be found in China. In my company, we have the equipments like S

We will be outsourcing all of our PCBAs and would like to know if other companies perform DVT testing, ESD, Emissions on all of your boards or only on main boards? Our shipping deadline is near and I would like to determine the risk in not performing

I think forgot one most important thing. SMT is not all. In China, after the SMT process, QC, QA, casting, packing etc. It need lots of labors. I really one worker can handle 4 lines. Nokia still have two bid factory in China, Motorola has two also.

Electronics manufacturing moving to China is not about the labor man. You all don�t get it. It�s the material, and not just the electronics material either. Plastics and metal parts costs are lower. Labor costs are the smallest component of a produc

Hi Guy's, Sorry about this, but yes it's another lead free related question. We are looking at using a Chinese SMD DC-DC Converter in a new design, whilst keeping one eye on the approaching Lead-free issue. The manufacturer claims that these are O

Dear all, Recently our production encountered high SOIC failure during testing after reflow soldering. All solder fillets (side/heel) are acceptable as per IPC standard.The reject samples (SOIC)being sent to IC manufacturer to verify the failure. Fin
