If I need to test whether our products can withstand the solder reflow process, is there any tests that I can perform other than putting the products through the actual relfow process.

I would believe that the connector spec is for the max temp that it can withstand while the paste is the max temp that you need to achieve. Solder balls are usually from excessive ramp rates in the oven. I would contact the connector mfg. and see wh

Can also reduce leaching of certain types of components. Also, dont expect to see a "shiny/bright" joint if running Nitrogen in the relfow unit, you'll see a dull/smokey like joint...if running Air then sure,let SHINE! my 2Cents DaveK

Most LCD manuf. specify not to wave or reflow. I believe this is because of the prolonged exposure to the preheat temp. However, about three years ago, we were running about 350/wk of a 40P DIP LCD through the wave with no fallout. It did stress t

When you say well designed for wave, does that include "extra" solder pads for the IC's for solder thieving? And Boards that are well designed for wave don't have QFP's on the bottom. They might be ok but then the board would be "ok for wave", but no

Your solders could have vasty different liquidous points. Check with your suppliers to determine the appropriateness of the materials you have selected. Awhile ago Jim Zanolli at Teka hosted an OnBoard Forum here at SMTnet. He'd be happy to give y

Hi folks, I currently use the supermole gold to do all my SMT relfow profiles. However, I've lost the charger for the supermole battery pack. If someone also use this tool and have their charger handly, would you please look at your charger and give

I just started a design where I will be placeing smt parts on both side of PCB. 50 parts on top side ranging from 0602 to SOIC8 and 4 SOIC LED's on bottom. How can I assemble with parts on both sides ? I have P&P,stensil printer, relfow and solder w

I have done experiments on small runs, with a few connectors and have had favorable results, I had apertures (oversized)made for the thru-hole connectors on our SMT stencil and hand inserted the connectors.. A few insufficient solders here and there

PizzaFred, Scott mentioned lots of good ideas. Take one of your boards to each vendor and see what it takes to program the board how long it takes for it to become online. I've found some that are easy to program, but require 40 or more assemblies to
