The 2009M is a water based flux and requires more preheating compared to alcohol based fluxes. After checking real chunks advice you might check if you hear sizzling when the solder touches the board (indicator that the water is not eliminated by you

We have a 3/6 Nozzle We do have monitors. One of our pots is leaded, the other is lead free. Our average wave height is ussually around 50%. Also, do you have any or found any benefits to removing nozzels at the end of your shift. I recall you say

IPA is a fire hazard. Be sure your fire extinguishers are charged and your evacuation plan is current, when using IPA in the vacinity of a wave solder machine. Have you tried DI water? Solutions used in wave finger cleaners include: * Techspray SMT

Folks, I'm looking for some specs for the maximum bend or strain that should be put on a PWB. Not looking at the solderjoints. I'm concerned with localized bending of the fab and what might be a reasonable limit for that bending. I've measured 105

Hi everyone I have Quad 4C with following problem. When I run machine "cold start" first power up it will run and initialize but after if I turn it off and back on it will NOT initialize. Z axis will push nozzle down and it will remain i that posit

This sounds like a Quadalign problem. Upon startup the Quadalign system checks runout of the Z-rod and tries to find the tip of the nozzle. It will keep lowering the Z-rod and looking for the tip until it hits it's limit. Check and see if the Quadali

I agree with RLM. What i have seen is that quad had a problem with the gounding system of the quad align unit. An additional ground wire was added at the quad align cage,and to the PCB located inside the front right access panel. I don't have a machi

thank you very much. In my case quadalign board is at rear right corner but it does not have cage just is fitted on vertical aluminum metal sheet plate.I will add ground wire to the board and aluminum plate from machine ground. I will post what is o
