| What are pro's and con's of reflowing top side first and curing bottom side chip components, and then wave soldering bottom side? | | How about curing bottom side first and reflowing top side later? | | What percentage of companies run reflow/cur

Jerry: You don't have to yell, we can see you fine Are your first side component going to fall off of the board or have their reliability affected during second side processing? If not, go for it!! Lots of people reflow through hole components.

You can't really use a pasted board to troubleshoot the program as any components not on target simply slide off with machine vibration and movement as they won't be held by the solder paste. Whereas on double sided sticky tape they remain in place

| Hi , | I have not been able to find any good description on how to perform double sided reflow on PCBs.The best would of course be to avoid reflowing the bottom side again but in real life this is not possible. | So when double sided reflow sol

Deon Response: Hello Will, Yes, you can reflow a double sided board using 63/37 solder paste on both sides. There are some limitations as far as the mass of the components to reflow the second time. If you have doubts or are concerned that a compone

| 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

You can get a report and CD ROM on pin in hole reflow assembly from the SMTA main office in the USA. They also have a new report on Double Sided Reflow Design and Assembly. | Hi all . | Thanks to Ryan, Brian , Justin and Dave for the timely help ear
