Hello davef, thank you for your reply. What do you think about the footprint for the diode on the first picture where the component is not assembled? There is good wetting on one pad of footprint and the other pad has bad wetting. This problem is not

Wilson, I'm sure both Electrovert (electra?) and Soltec have machines in their rangs that will open to this size... Out of interest...what type of board is it?

Deon, my first response is YES - big time. You are correct that there are some massive issues here. For one thing, lead free solders are only one solution, as conductive epoxy has also been put forward. This was demonstrated on the TAC line at Ne

Hello, Going to be setting up a no-clean process for thru-hole components. Any guidelines i can use. Know the basics but want to make sure i am not overlooking any steps. Thanks Wayne Sanita

Rob, We are also using intrusive reflow to simultaneously process SMT and Thru-hole components. Our arrangement goes as follows: - Screen print solder paste to the single sided PCB using 0.008" laser cut stencil. - Apply adhesive dots to selected

During the solderin of a double side board, how can I calculate the maximum weight of a component I can put in the first side to avoid the component fall down in the oven (depending on the soler join surface) ? Are there some rules ?

Dave, Thanks for your quick answer, I read some paper on the forum. I would like to learn more and to know how to obtain the result of x gr / sq in (mathematic methode). Do you know where can I found it ? Thanks. J Michel

One thing most over look is the time between the last reflow and the second print. You don't want to print on a hot board.
