Hi Nikhilesh, It was a long time ago, but we used to buy the nickel in reels then had a cut and feed station on the smt machine with selectable sizes. We did many types of boards in very large volumes, and usually the Nickel strip was soldered to t

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

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)

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

Are the jobs so small and the setup time so high that it precludes running them on two or three machines?

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

We have several selective soldering machines, that because of several minutes of process time per PCB, one operator can keep 2 or sometimes 3 machines loaded and running. Other days only 1 machine is running but operator does not have enough time to

For me it looks like a scheduling issue. You can do time studies on your assemblies and predict the best workload, based on scheduling the jobs in the right sequence. Also it sounds like you have only one operator. Train more people to operate will h

hello guys ; we are using some standard selective wave soldering unit used in lined ; the drawback of a such machine is 1/the speed which is quiet low (the board is coming on position through the conveyor, then the head delivering the solder moves s

Check flux penetration and type of flux. How much is solid contents. The solder filling is better under Nitrogen. Check the time (speed) of the nozzle whether is correct. Usually For SAC305 the temperature of bath is 320C/degrees, but only for sel
