| Hey all! | The wave solder warrior is back. I have found a flux which leave almost no residue (the least yet), but because of its super low solids content I absolutely cannot get topside fillets. The multi-layer, two sided board is on a pall

| | I'm reviewing my board fab spec. It calls for a minimum SnPb thickness of 50 microinches on HASL PWB's. I've looked at other specs that call out anything from 30 to 80 microinches, and others that just say the copper pad must be covered and sol

What is the surface finish? HASL, Entek? what? If HASL, ask your fab supplier for recommendations, maybe even rerun the boards through the HASL process. The fab house would have to strip off the old coating and reapply. Just a thought, depends on y

I've a query. I have one new Customer whom insisted us to use RMA paste on their product. The problem is, on some of their products they use via hole as the test point in where all the PCB finished are ENTEK and as usual I have to print solder paste

Hi, In 2006 we will need to produce Lead free PCB and for now it's hard to get answer to my questions. I'm from Canada and the PCB vendors we actually have are not ready to produce Lead Free PCB ( HASL Lead Free ). For sure OSP (Entek) is not good

Thanx Dave/Hussman.. We normally store our solder paste in the refrigerator at 0-10 Deg C as per what the supplier recommanded. Our floor temperature is controlled at 22 +/- 5 Deg C and Humidity is at 55 +/- 5%. Recently we have customer asking fo

| How can I solve the small solder ball in the N2 W/S ? | The Oxygen level is 10000~20000ppm & no-clean flux. Yuen, Sorry I an't got an answer, just more questions. 1-2% O2 in your wave solder - are you running membrane generated nitrogen? I don't
