The variables to study: * Dwell Time * Contact Length * Conveyor Speed * Parallelism * Top-side Substrate Temperature Before wave * Solder Pot temperature All of these variables are inter-related (ie changing one variable will affect another)

Canyou see this contamination? Is it solder beads, flux or something else? If flux, then more cleaning should help, either more time, more cycles through the cleaner, etc. If it is solder beads that are not melted to the rest of the solder, then s

Dear all, we are using the lead-free SN100C solder alloy for wave soldering. We are experiencing wetting problems each time we have to solder a thick board or a board with a large ground plane.I think that maybe we are not using the right flux. I w

We just obtained a Radial 5 Inserter with no documentation on how to run the software or to operate the machine. All I have is some hastily handwritten notes from the limited instructions that the installer gave me. Does anyone know anyone who has

I meant have the board shop build the boards. I'm not talking assmebly. With the Occam process it would be like waiting untill you have all the other parts then phoneing the board shop and then ordering your raw pcbs. The interconnects have to be

A long time a go I designed Wave Solder Pallets for lead based solders, but having been out of that industry for a number of years I need to design some new pallets for lead free. We used Titanium to support and mask areas of the board and that work

Ben, I'm not aware of any 'automatic' method to convert PTH footprints to SMT. Typically, many of the components are passives, and there may be a way in your CAD software to change the passives of a common size to a different footprint. That will co

Hi Experts, Understand from my friends, PTH crystal can get damage easily when subject to vibration or heat..For example, if crystal drop from table to floor, its internal part already damage @ crack which cannot be seen by eye. Besides, they als

Good afternoon, Oops. Quite huge difference I must say. But you should try to tweak your profile anyway. First of all try to enlarge soak time as Mr. RDR has said. What process type do you use? Lead or lead-free? By the way, there are lead-free proc

We are testing SAC paste for thru-hole components in the 2nd reflow process. The solder joint is alright but some problem encountered in FR1 or CAM2 PCB after multiple times of reflow due to the temperature. We are very interested in Zn or Bi-based l
