Hi! From your post, it seem like the wave did not really touch the component. You probably need to get the both wave height correct and that it hits the component.It is normal for solder to come through the PCB when using chip wave. The through-hole

Check that you are getting an even spray pattern from the fluxer.Check that the chip wave nozzle is clean and if possible feed the PCB in to the wavesolder unit at 90 � or 180�.

Hello !! I have a problem with my wave solder oven, in one of the products we made has connectors on one side of the pcb and in the other one has SMT components the process is kinda tricky on the SMT components we use an adhesive and put to the refl

Hi friends: I have a problem in the process of one PCB, I have a lot of insuficients of solder in top of the board, this pcb already was working good, but sudenly began there isn't flow thru hole, I ran the profile and it was ok, if I inmerse i

Can anyone advice me on the effect of SN100C wave solder on SAC305 hasl board? I suppose the silver content on the hasl pcb would leech(contaminate) into solder pot.? Would it affect the surface bonding between copper pad and the solder.?

We have a problem with our Unleaded wave solder machine only randomly soldering some pads. I have looked at the flux level and that appears fine aswell as cheking the preheat and solder height in the bath. The probelm is not exclusive to one perticul

Yes pads are still gold after the wave soldering process even if you wave solder a pcb several times. I have tried soldering using an iron and the solder takes to the pad as you would expect. This happens on all boards of this type and all boards are

Are you spray fluxing ? If so, check that you are getting flux onto the whole pcb uniformly.... That BLT flux is a water based material, are you getting rid of all the water in the preheat before you get to the wave ( can you hear any spitting as t

Hello Ramon, This is a very common problem that usually can be overcome. Can you tell me the flux type you are using (manufacturer, and flux number)? Has your board vendor, or type of PCB's changed (are they entec coated - bare copper)? What is t

Measured the pot temprature independantly from the software (268C/514F from moving wave). We are using Dross Inhibiter Tin/P Regenerator from BLT. Monthly sample checks are carried out on the solder bath and are all within limits. It will be hard to
