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

thanks again for reply, we have now configured speed of traveling so pcb can travel through preheat with one speed (call it v1) and through wave with other speed (call it v2). Lenght of preheat elements is fixed, so with speed v1 we can change pr

Are you using water based flux? Any preheaters on the SS machine?

suggest you check the preheat conditioning in the wavesolder process is sufficient, as this is the main culprit for micro-crack CAPs ?

what, no top side preheat?
