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

we worked out that the wave soldering cassettes Duratstone material takes alomst 35 degree away from the surface of the pcb, and the speed is already too slow it should be over 1.0 - 1.8 meters a minute but its now already 82 cm a minute, in order to

Deni, When using a no-clean flux preheating is a critical parameter. If you don’t have a thermo profiler you can use inexpensive temp. labels See link http://www.coleparmer.com/catalog/product_view.asp?sku=0806822 or Google Temperature labels If i
