Hi, I am looking for the IPC criteria hole-to-lead ratio. Does anybody know a practical way to determine if some holes in my pcb's do not get enough solder in the wave solder machine because an inapropiate hole-to-lead ratio? Thanks in advance! Hi

I own and have read this book. While it is better than the average soldering book, it is not the first book that I reach for in trying to sort through a problem. It introduces a broad range of soldering methods with a reasonable amount of detail, b

I'm not sure if I understand the question correctly... Mainly, drill the mushroomed end of the rivet with a drill bit that is slightly larger than the shaft size of the rivet and remove the cover. Then, you should have easy access to what you need t

It sounds like the process is very labor intensive, and all the verification is done after the parts are soldered. Assuming you are hand placing the components: 1 - Contact Systems semi-automatic placement machine. It show polarity when placing, so

Does anyone have a suggestion for soldering boards with 1 inch long leads sticking out the bottom? Our vendor is using a drag solder machine, but I'm not happy with the preheat and controls on it. We assemble boards with numerous LED's( 200 to 700 pe

Mike, It sounds like you have a serious problem, I don't know much about drag soldering or what your specific soldering problem is with your present supplier. I do know that with a conventional solder machine these leads won't even make it through

Mike, A drag solder system is not so bad. If it's not discoloring the silk screen , damaging your parts or blistering your boards than it looks like a safe bet. I am not sure what other components you have on the boards besides the LED's? But the

Mike, Russ is right, no 'normal' wave machine will solder PCB's with 1" long lead length. I have seen waves modified to clear up to 5/8" leads, but the deeper the wave the uglier things get. They get uglier in that a lot more dross is produced, con
