ok, sorry ,750 was deg F and which I said 350~400 were deg C, I got a mistake. As I know, we use 660~720 deg F to do reworking for lead free solders such as SAC series and SnCu0.7 series solder to protect irons and components on boards. when temp.

Dave, that's good thread, but I think Mike is more concerned with the Titanium inserts that pallet manufacturers often use to overcome sh*tty designs - like the ones where they put a Through-hole 2mm away from a SMT pad. He's not so concerned about t

1. If I go to the Pb-free solder paste, is it necessary that I have to change my reflow oven OR just by changing with respect to solder paste specification, I can reach my goal? 2. What is the �Low- Temperature Phase� in any solder paste alloy? 3.W

Boy, I step out for a bit and everybody picks on me (just joking). I believe I may have been off base a bit. Checking every bit of your stencil design is very good - I do that too. I calculate LXWXH and reduce or over print where needed, depending

Steve, I have no influence over conn design. We paste print-reflow solder two types of connectors. One is a 50 pin IDC w/ 0.5mm lead dia @ 2.54mm lead pitch and a chamfered pointed lead tip. The other is 32 pin DIP w/ 0.36mm lead dia @ 2.54mm pitch

I do not agree with that. Stainless is typically used and it works fine. We run many different paste types, RMA, no clean, WS, PB, Pb Free. No sticking issues. You can spend the extra money and buy coated blades but it is not necessary for most ap

Make sure you check the MSDS for the new paste. If you have more than one production line, I'd suggest a gradual changeover. One selling point for management would be the free training Multicore will give you for the switch. If you haven't already
