we are manufacturer of molded type transformer and we soldered are units using wave soldering machine and then we washed the units to remove flux residue. what materials or any process for us to eliminate the process of washing after wave soldering.

What manufacturer is it? I usually stack the bars in as tight as possible. Especially against the wall of the pot with heaters. While it's heating keep applying slight pressure with a bar of appropriate material, towards the sides to facilitate melti

Hi Stefano, Although your concept of Wave soldering such devices is possible, I would look at an alternate solution. An easier way would be to Reflow solder all Bottom side SMD components with solder paste, followed by wave soldering for only through

Keep in mind that device pitch, pad geometry, lead length and even alloy type will play a roll in your evaluation. I have an assembly that we run 10k pieces per month. One two-pin connector has a pitch of 1.27mm. Unfortunately, the pads are 0.007"

Hi Joris - There is an excellent wave solder guide called "Take No Prisoners" that includes instructions for attacking and eliminating solder balls and preventing their recurrence: 1. Increase Dwell Time Solder balls are normally caused by too much f

Hi, what is minimal time for fluxer to prepare for fluxing another frame ? Is it possible to run through fluxer frame after frame without any spacing between them ? Thanks for any comments, Andrzej

The hole is too big, you should reduce the size in the next PCB revision. The middle joint is soldered at low temperature you can see how the solder didn't distributed evently and cooled on waves. The solder joint at the bottom didn't wet the capac

Thanks to all for their inputs. @Hexielectronics, I am now trying to assemble the board by attaching it to a frame and removing the frame while waving it. I plan to put the boards back on the frame after the board cools down. Could you explain more

Our best suggestion - get the copper balanced and if possible go to higher Tg materials.

Thanks for you suggestions, guys. davef, I am gonna get with my PCB suppliers and talk to them about copper balancing and checking the Tg of the materials they use. SC, I am working towards designing wave pallets for my boards and try your suggesti
