Istvan, One possible reason for this is that you are using a water soluble flux in your wave solder machine. If you are and the boards are not pre heated long enough, the water in the flux does not evaporate before hitting the wave. When the water

Hello We sell soldering stations that can heat up to 200 celcius in less then 20 seconds. The temperature settings are variable and can be pre-programmed. The stations are very competitively priced and can handle home soldering applications. Please

We are using selective soldering pallet, which the soldering flux is Interflux 2005M. We encountered the poor hole fill mainly at the heat sink components. Initially we tried to apply more heat but tend to overkill the flux activity. After some modif

Concerning the solder-balls, there are a few causes for this. Try to slow down your solder-speed (P.e 80cm/min). Can you measure temperature after the pre-heat zone? Are there also blow-holes in the joints? Personally I think there is some water in t

We use an LM2575 switching regulator, and have had no trouble reflow soldering it. It is made for that purpose, so no big tab with the bolt hole, and the leads are pre-bent for SMT. Note that soldering the part to the PCB doesn't really give the he

Anyone have problems wave soldering white tin finish? We are an ems and our customer provides us the pcb's. SMT and TH components on the board. SMT is fine but when we wave solder, wetting to top side is very poor (solder only flows half way up). We

Hi, I have a Fisnar I&J500 Selective soldering robot that has failed. I think it is from around 2000. The Fisnar I&J500 base has a soldering attachment on it. As I understand it, the base controller sends it a 5 bit command to the soldering unit. T

We haven't run a profile yet....probably because we're a-feared to. We can't do topside preheating here to any degree because we use an aluminum plate for aligning hundreds of top side through-hole components (pots, switches, buttons, LEDs) that te

Hi everbody, I'm facing some soldering problems with a Diode (SMA) during wave soldering process. During this process almost all the time one of the component pads have no solder, according to the picture dsc000604 attached. Some considerations: * T

Have you check the flux gravity lately? If not, Check the flux gravity every 6 hours to make sure proper parameters are meet. Here is a list of things that may cause your solder ball problems; Excecive heat, defective fixtures, preheating temperature
