Hello We sell soldering stations that can heat up to 200 celcius in less then 20 seconds. The temperature settings are variable and can be pre-programmed. The stations are very competitively priced and can handle home soldering applications. Please

I do recommend dedicated tips and dedicated workstations. Make sure that your tips come in with no lead in the tinning. There is a new, green heat resistant table mat that is being used in the industry to identify lead free areas. If operators see gr

"Too Hot" is any more heat than what is needed to reflow the solder. You should have the Auto-Profile software for the machine, this will accurately monitor and record temps. There is also port for the component itself to monitor package temp. There

We've also seen it where a component has had a long soak at a high temp (last one was 220C for 1.5 minutes)without exceeding PBT. The long soak was due to the oven only having 3 heated zones. On the last occasion there was some concern over the lea

Why is your big heavy BGA profile your fastest one? I'm guessing because it's hotter therefor faster? To achieve some kind of "balance" with the others. But you want those boards to get more heat, so you don't blance higher temps with faster belt, yo

whats the actual failure mechanisum your seeing which balls on the BGAs? my bet is its the ones on the corners, this is mainly due the the large heatsink on the top of the BGA when it starts to get hot it acts as a bi-metalic strip and lifts the corn

This is a bad situation and if you use (better to rework) adhesive that means it will work worse in your normal process(wont hold). Heat all the leads to reflow temp, twist (rotate)the part untill it breaks free. Most adhesives are not designed for t

for sure it's an excelent topic, in Mexico we've used almost any brand in the market (Research, Heller, Electrovert, Rhem, Vitronics, Conceptronics, BTU) and after all those names, we could see that Vitronics is a good opton, good service, not too mu

Looking for idea''s on how to reduce cracking of components along viscore. We are placing within 0.020 and0.030 from edge in some cases but are seeing cracks on components placed all the way out at 0.150 off edge. Has anyone heard heating the boards
