Our process mostly are double sided reflow and we are using water soluble paste on ENTEK PCB. Rework WIP has been accumulated since the last 4 months, and upon clearing, one of the method that the test guy use are to reflow the PCB again for one mo

I need to setup an oven to run with a nitrogen atmosphere for boards with BGA's, but our ovens do not have the optional atmosphere monitor and controller. Is there a good way to sample and control the atmosphere without the optional built-in atmospe

Thanks. I have another question. I believe this machine was originally set up to run nitrogen. In the cooling section there are two chambers. One with a radiator air/nitrogen knives and the other section/chamber has a blower. Instead of running nitr

Oh silver and its...improved solderability over tin / copper. BS if you ask me. Look to your flux and thermal profile for wetting spread. Ask yourself just how much "wetting spread" do you need to fill a barrel? I have the same 100% barrel fill

| We have a Vitronics SMR400N oven and many times need to use N2 inerting. My problem is that it takes close to an hour of operation to purge the system to achieve the desired O2 levels (~40PPM). This is not only time consuming but results in an inor

We do in fact see a reduction in soldering defects, most especially wetting issues for both parts and PWBs, tombstones, billboards, etc... As a CM we see all kinds of customer furnished material, some of it not in the greatest condition. Our best p

Numerous people use the Pyramax oven to process high temp solder but your success will depend upon the mass of your board. To maximize the probability of success you should use the highest convection rate (IWC) possible to enhance heat transfer an

Hello all, I am having soldering issues with an Everlight component it is a TM4201/TR2 (Right angle IRDA with a 1mm pitch). The problem I have is that after reflow the solder joints look perfect, but during test we are losing 7 micro amps as soon as
