Looks possibly like the ground is sucking the heat away. look at your preheat? is it getting to 120c before wave?

but we do not have laminate preheating on robots. There is no flux separate application, the flux is in the soldering wire

You will need to preheat the boards for a lead free selective solder process. A preheat module is critical for any wave or selective solder process, if you don't get the board preheated properly the solder is going to resist flowing to the top of the

Note that the TF2800 features a large 7 panel preheater with an adjustable height component that allows you to adjust the height of the IR preheater to get much closer to the board. This feature multiples the power of the preheater exponentially, so

Try preheating the connectors

Hi Gary: I'm sorry for not being clear. You should be concerned about the change in temperature between the end of preheating (actually just before the wave) and the wave. So, it is the difference between those two temperatures you should try to k

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

Can someone please advise me to the rework procedure for removal and replacing Ceramic Chip Capacitors (e.g. 0805, 1206, etc.)? Is it necessary to pre-heat ceramic capacitors before soldering them onto a PCB with a soldering iron? Is this just a rec

we have some rebuilt wave soldering systems in stock ready to be shipped. epk-ii smt with lambda wave, chip wave ,omega wave. 4 preheaters,jacking stand roll out computer control. machine is in a great shape. another machin upk15f with 6 preheaters
