Hi, We are using 10+2 reflow oven ( BTU Pyramax 150 ). We have tried with short TAL ( RTS profile too ). As of Now we are using the attached profile, which has given us lot better results. But the issue is not eliminated. Thanks

Lead Free SMT 1. Stencil printer Squeegees s -should have Pb free pair 2. Reflow oven - should be able support Pb- free higher temperatures. 3. In case you have inspection table on the SMT line - should have Pb-free mats(usually different color)

I have a question for N2 reflow, I want to know how difference of the O2 PPM in reflow oven then get the result? Now, we use the N2 to purge into BTU oven and measure the O2 PPM is about 1,000. but cannot find the difference to compare to compress ai

Multiple reflows

Thank you guys. You keep adding valuable information here. I think we will try to stick with the 3 times reflow(if we count the BGA repair as 2 reflows). However sometimes we will run the board second time through the oven(just flux the suspect part

Multiple reflows

In agreement with Evtimov. Max 5 reflow cycles. Something like this scenario: Build bottomeside 1 Build topside 2 Reflow topside for suspect opens beneath BGA 3 Remove BGA during rework 4 Replace BGA during rework 5 Any convective rework after that,

The story so far!

Some production problems we've faced: 1) Delamination; 2) Reflow fixture distortion; 3) Obsolete parts; 4) Failure of blower motor bearings in older reflow ovens; 5) Poor toe fillets with miniSOTs on thicker PCB's; 6) Lack of updated component data s
