Since we use tons of different fluxes and chemistries we clean often. A quick trip to our batch cleaner- run one cycle.....back to the bench. We have no control just a weekly thang. When the sponge starts to deteriorate then it is replaced. Caldon

I have difficulty to convince my management to air-condition our manufacturing facilities. The room temperature fluxuates from 8 deg.C in the morning to 25 deg. C in the afternoon. The PCB topside temperatures in the reflow oven and wave soldering ma

Hi, I know for sure that by controlling temp. and humidity conditions in SMT assy lines room, one gets advantage in screen printing, adhesive dispensing, and pick&place machines mainteinance. Does any one have any advice on why else is a clean room

What do yall do to control the configuration of placement programs written for a specific product? We always just ran what was on the machine, If the first piece looked good, we ran it. If the first piece looked bad, we fixed and then ran it. Now

Hi mate, suggestion: consider "re-fridge" the paste after each Lot (small volume) batch run, instead of leaving it at ambient temperature for 3mths. follow FIFO control of such re-fridged paste. check with your supplier (in documented format reply)

We are assigned to set-up an ESD control at a new site. There are a few proposals in mind, they are 1) conductive flooring with heel strap or shoe 2) wrist strap with continuos monitoring 3)the normal wrist strap with the common grounding point. Woul
