Hello Everyone! I have encountered a situation where I have surface mount components on the backside of the board and I need to wave all the through hole leads on the backside as well. Can this be done? I thought of the possibility of adhering the

Nowadays I have a problem, I am in chsrge of the section of smt in my company, have a normal process inside my department with a minimal level of mistakes, the problem happens when the material is liberated to the lines of production on happened for

KA, Joshua makes a good point. A wave solder fixture will allow you to process your double-sided boards without having to add the epoxy step. The one time fixed cost of a fixture is quickly offset by the time that you save by not gluing your SMT.

Sure KA, it's done every day. Be sure that the components to be used on the bottom can take the maximum heat of the wave and the delta T of entering the wave. Depending how complex the bottom side is you will get better results with attention paid

If I understand what you're saying, you are reaching reflow temp's on the top side while soldering bottom side components. You might want to run a glass gauge plate over the wave and make sure your contact pattern isn't too large. If your PCB is in c

if you wave solder you have to glue the SMD parts on the bottom side. If you reflow the bottom side then you usually shouln't go over the wave afterwards. It's quite logical the joints melt again, that's what you want to achieve going over the wave.

Hello KA, When producing in kind of PCB product you have to base much of your decision on cost effectiveness, time, and quality. In order to get the best of all three you have to decide which you want to be your top priority. By adding an epoxy to

Like Mark, I'm guessing your problem is with SMT parts on the top side, the solder is re-melting and some of the parts are moving around during when the board is being wave soldered. When I had some training on thru hole wave soldering way back when
