I'm not a Wave soldering guy and my friend have asked me a question on what is the best preheat time and temperature for Wave soldering.They experiences only 10% flow up thru the PTH barrel. I've asked them to increase the temperatue to 120 Deg C. Cu

If you will place a temperature strip on the board during wave soldering process you will get a max of 210 F or 98.8 C which is normal on the standard wave temperature. The problem on the 10% solder on the TH via hole can be caused by insufficient fl

Hi , As far as I experienced with wave reflow. If u have a refective thermal reader , u will see that the board is exposed to much more temp than the 120 deg that u set. Actually , once u see the board warp or comp. crack u should know that

SMT Experts, Hi, I have a pondering issue, which is : Our current specified Reflow preheat timing is a necessary 100~140sec for the ranges of 100~170Deg-C....obtained timing is 77sec... out of curiousity, if we further fine tune the obtained reflo

A good guideline is keep it similar to your wave solder process, for example 2-3 sec. This assumes you're preheating the assembly. While polyimide boards are fairly robust at some point you will begin to see copper dissolution - the solder side pad

Hi Joris - There is an excellent wave solder guide called "Take No Prisoners" that includes instructions for attacking and eliminating solder balls and preventing their recurrence: 1. Increase Dwell Time Solder balls are normally caused by too much f

Have anyone perform wave soldering on FR-2 and FR-1 printed circuit board with lead free soldering? Can you share the parameters(wave temperature,preheat temperature, contact time, wave height,etc,) used and did you do any changes to the wave solderi

A common bottomside heater configuration is IR-Convection-Convection. One of the big advantages of the IR zone is its ability to allow the flux carrier to spread and dry slowly before the board reaches the convections zones, which can blow wet flux c

Hi Dave - You are correct that I was not clear in my comments. I assumed Joris had seen the usual solder balls accompanying his blowholes. Nevertheless, Joris, my first two recommendations still stand. Increasing the dwell time of your leads in t
