Hi You all We use no clean flux in our lead free wave soldering process and have unacceptable residues. The provile is spot on. If I reduce the flux amount the holes won't be filled and border on the IPC II specs. The customer does not accept partia

Hi, I'm just wondering if someone have more information about board with immersion tin plating. I search in the archive but didn't find anything interesting. We try it, and we have difficulties to make a good solder joint with the wave. And wi

What you can do is perforate the board holding rim by drilling holes of 0.6mm (similar to via's). This will reduce the mass and heatsinking capacity, allow excess flux drainage and facilitate convection heat contacting the board through the holes. Th

Hi, My company is using HEPA filter to improve air quality coming out of oven/wave solder. But the cost of such filter is quite high and we need to improve the consumption. Any suggestion from fellow experts out there? a. Anybody did a cost reduc

Hi John, Are you talking about cleaning the pallets after running to store them? or during production? well in any case...I recently started to use this cleaning solution "Cybersolv" from Kyzen. It is water soluble and also can be used instead of IP

I was wondering if anyone could help point me in the right direction on this one. This morning I discovered that our hand solder operators have been using the liquid wave solder flux for some hand soldering operations. We are using Kester 245 63/37 n

Listen Samir, we some times spray the tops of our baords at wave to achieve top side wetting. Not sure if the engineers aren't setting up the wave right or not, but it gets the jwob done. We don't see any fall out from this and have been doing it f

Hi, Thanks, and we are doing that today. After spending the day playing with all the usual things that used to work, we are focusing today on profiling and data to get things right. The only worry I have is did we get a wave that can handle this, a

nice to hear from you..my company is an ems.so need a more flexible reflow.. we have 3 lines and soon to install another line for leadfree ideally..so.. its getting a new one hopefully..a seven zone actually i think might do the job... for the wave i

Thank you all for your input. The MF300S Multicore flux is rated for lead free. There is not much dross or contamination. We are using nitrogen. I've tested the boards with the curing test of IPC-TM-650. I think you're all right about the preheat.
