My experience with different size boards and pre-heaters. The perfect world (right?) you would saturate the complete pcb with bottom pre-heat. But it is difficult with repair and rework equipment, not to mention the expense and foot print of large pr

We (ETS) are a manufacturer of reflow, curing and preheat systems and have had similar requests from customers in the past. One in particular required soldering onto an aluminum heat sink weighing approx 5 lbs. You might consider selective/robotic so

Hi Ed, It all depends on more info needed. How many preheaers do you have in your wave? One, two, three? Are you talking bottom side preheat? What size boards do you run and what type of parts are on it. Typically, preheat does several things; w

Thanks for all of your suggestions. I ended up borrowing a Pace Worldwide PH100 Preheater, which worked like a charm. I'm in the process of purchasing one for our own shop. I had to place the aluminum pcb directly onto the PH100's ceramic heating pla

Hi Joris - There is an excellent wave solder guide called "Take No Prisoners" that includes instructions for attacking and eliminating solder balls and preventing their recurrence: 1. Increase Dwell Time Solder balls are normally caused by too much f

What are the factors that go into determining PCB Board temperature requirements for the Wavesolder process? Most of the recipes I've seen call for preheating the PCB to around 230F - 250F. This temp is about 210F - 230F below the typical solder temp

Kev, I looked up records of various hollis machines with 3 preheat zones. and with progressive preheat temp. of 300 400 and 500 with a speed of 3.5ft/min the topside board temp was 120C before entering the wave. the preheat elements were infrared. W

Kev, It looks like you have a preheating powerplant and you still only get the board up to 85 Deg. This indicates that the preheating is out of calibration or the range settings might be very wide (Fex the preheat elements shut down at 500 and go ba

We do not have problems with preheating. before we used to suspect that the cause of tombstone was that because the semi-auto and manual version do not have pre-heat stage. We had 1 with an IR heater and it is quite okay. you can use it too to cure a

A little more information on your current wavesoldering process would be helpful in helping you. Information like what kind of flux your are using,how you are applying the flux,what preheat temps you are using,and your conveyor speed. Without knowing
