Hello, I am looking to change from hand soldering to a dip soldering method. The board is double sided (only one side has components though) and has all through hole components currently. I would just like to know if dip soldering would be the best c

Samir, From experience, the only board test situation where tented via's have difficulty with contact is with a Flying Probe type tester. Otherwise, for traditional ICT, the force of the pogo pins, correct probe type, and fixture design should do th

Hi Experts, We have requirement from our customer to control the PCBA flatness at 10 mils diagonally. Weird but this is the requirement due to the need for some through hole pins (spreaded acroos the board must touch the copper sheet while they are

Make sure your reflow profiles are the best you can make them. You will probably want to, at the very least, get some sample BGA's and boards to sacrifice to profiling. Drill a small hole through the board into a middle ball of the BGA. Also put a t

We don't agree that "a little to the top would just even things out". The raw flux on the top of the board never touches the wave and so, does not receive the proper amount of heat for activation, except at the through hole barrels. * We assume WML

Your concern should be do you have a glue process that can keep up with the FCP6. We ran a GL541 in line with a CP643 which the glue machine was actually a bottle neck because if you run SOIC's which require more glue dots then it will slowdown the

Moon man was guy who contributed often to smtnet. He had a lot of experience behind him. He breathed nitrogen, drank flux with an occasional shot of 111 trichloroethane, and his lunch consisted of dump bucket vision rejects. He was originally crea

Really Rocky? What's the meaning of Russ' "if it will fit" in your scheme? As an alternative to your scheme, he could glue the nut on its side, tie a string through the hole in the nut, attach the other end of the string to the open door, and the

Solder preforms can be used in SMT assembly for through-hole pin-in-paste process. In this process and modified aperture is used to print the paste with standard stencil printing, then a solder preform is picked and placed by a machine into the solde

Dave, I've seen some instances of solder as you mentioned "painted" over the joint. Almost looks like a seam between the added solder and the originally waved on solder. Typically, I've seen that in the past from an incomplete solder joint. One w
