You will need to preheat the boards for a lead free selective solder process. A preheat module is critical for any wave or selective solder process, if you don't get the board preheated properly the solder is going to resist flowing to the top of the

It could be lack of preheat or flux. You can verify the flux by hand applying. I'll bet it's lack of preheat though. That's usually the case with selective solder.

Low end selective laser soldering systems are limited to what types of soldering can be performed. I have read through the previous comments and find that most have commented on earlier technologies (which do not offer the features today's system do)

There are several types of lasers to do laser soldering. Panasonic also has a high intensity light that can solder as well. I've tried em' all and two over whelming things stand out when it comes to this type of soldering. #1 is preheat. It seems

Try add a pre-heater. If not change the process or the machine. With KISS you will hardly get any PCB to work properly.

HOW THICK IS THE BOARD? IS THERE A LOT OF COPPER IN THE BOARD? DOES YOUR CUSTOMERS PROVIDE HEAT RELIEF IN THE BOARDS BARREL DESIGN THERE NEEDS TO BE PLENTY OF ROOM FOR LEADFREE SOLDER TO FLOW, DID YOU CHECK YOUR PIN(LEAD)TO HOLE (BARREL) RATIO? N

We use both types in house. We started with a board moving over the pot, slowly moved on to Jade machines and eventually Synchrodex. Like you mentioned without palletizing you'll have component movements during the cylce and most likely won't have th

Is the process the same for every product running through the selective solder machine? Load program, acquire or set up fixture, Change/load flux?, Change/Load solder pot? Are the machines cold when the operators need to use them or are the machin

All the response is appreciated. We have 4 SS machines and 2 operators (normally). Some jobs take up to 15 minutes (multiple boards), some take less than 2 minutes (machine time). Some involve fixtures, preheat, some may require the operator to mon

It's been a few years, but lack of preheat was my problem with this machine.
