We are having issues with top fill and dropping pins on Molex connectors with our KISS 101. Unfortunately we do not have a pre heater and bottom side pre heat with our nozzles is not satisfactory. Most of the issues occur when using a no clean proces

We have had some discussions about what causes parts to lift out of the holes when going over the wave on our flow solder machine. The machine being used is a Treiber (700 series). There are two bottom pre-heaters and one top pre-heater. We try to pr

I think he did mentioned the board size in the inital thread: "265mm x 207mm pcb", but maybe it was not clear written. I have a question about rework and pre-heat: is it necessary to have the pre-heater to cover the whole board size, even if you onl

A key factor is underside Pre Heater ----- Conceptronics makes the best in terms of IR Preheat----- Most machines have forced convection from the top and bottom --- the preheater is the key on larger more dense boards. Placement accuracy is also bett

Anyone having any conveyor rail shaking on Electrovert wavesolder machine model "Electra"? The conveyor shakes more with a pallet passing through the machine, particularly when the 20" pallet is passing from spray fluxer to the first pre-heater. Here

snip | | Dear John/Earl | | Thanks for your clarifications. To me also the problem does not seem to be linked with the PCB. The Pre heater temp. is set at | 450 degree C. We are using Alpha Aq. cleanable flux. Can you elaborate on the Desired

Unless your wave is very, very, very old - you are having your leg pulled. Or someone in your maintenance dept. is a little out of it. Most pre-heaters are already coated to prevent rust. Maybe the coating has flaked away, if so, I'd suggest using

We do allot of multi layer boards with heavy ground planes or heat sinks attached. We have a Trieber, use RMA flux, solder pot temp at 500F, foam fluxer, spray the top if need be, and would warm up the PWB to around 240F over the preheaters. We have

I use to have that kind of problems with other type of machines and here are the causes: 1- Spray fluxer head partially obstructed (check flow rate) 2- Defective pre-heater probe (manually check temps) 3- PROFILE (last preheat to 280) 4- we sometimes
