In general, it depends on what you're working on. Boards with a higher thermal profile might require higher temps. But...the usual answer is...set your irons to the lowest temperature possible that still achieves the goal. We usually keep our ir

I was handed the task to develop a process to solder a BGA using topside heat only. It is a long story so I will spare the details, but I was wondering if anyone has ever attempted this? I have been going at it for a few weeks with fair results, but

I have experience of Immersion silver and it's even more sensitive for all disadvantages mentioned above than Immersion tin. You can not go wrong with ENIG. It's little more expensive but in the end you save some bucks when you don't have to rework o

Agree. However the LGA has an even lower standoff, so I would think it would be an even greater challenge. The LGA is a cheaper choice but want to know from those who have done both if the extra cost of the SnPb BGA would pay for itself in lower rew
