Hi, My Bottomside component pads are 1:1 with my topside land sizes/dimensions. I have difficulties catching solders on my bottomside smd chips (SMB Diodes, 0805 RC Chips). What should the bottomside components for wave soldering be greater than my t

I currently have a board that has several wires that need to be soldered into it. Many years ago I remember wave soldering power supply boards that also had many wires. In order to keep the wire insulation out of the solder fillet and keep the wires

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

Tell the board shop to increase the cure temp of the resist as it is undecured especially if you have waxy/greasy resiues on the board and a brown tar like substence in the solder wave itself. If undercured then solder will not flow off the resist pr

We are facing a problem of high contamination on boards after wave soldering. We want the contamination to be under 24 ugm/inch square. We are using a no clean flux with the spray fluxer unit of wave soldering. The contamination is higher on the end

I' designing a PCB with SMD components to optimize the land patterns for wave soldering. I find that the IPC-SM-782 land patterns are not robust enough for wave soldering, yielding ramdom skips and bridges. This PCB will also give me insight on sha

please download the picture from the link below . we have two picture . picture1 is the place of the 96 pin connector that we have problem with it and i should say that we use parallel & perpendicular direction for sending the board to the wave solde

we have problem in setting the density of a no clean flux for using before wave soldering . first we dilute the flux but we have many short circuit problem between the pads of edge connector,then we densify the flux all the short circuit is removed b
