All of the discussion of "environmental controls" are a matter of degree, dependent on the requirements of the product that you manufacture. For example: shops assembling under-the-hood products have different requirements than shops making garage d

Joe: Hey, just hose everyone down with water when your humidity starts to decrease to below 40%. ;-) Actually, that�s how some humidity controllers work, when added to your heating system. Well basically that�s how they work. I�m not tryin� to

Process control for Photonic soldering is based on the actual temperature of the component being reworked. If the desired temperature of the component for your process is 200C then that is the process temperature programmed. This is achieved by a cl

The tendancy always has been "when in doubt, touch it up"... this is not the way to "verify the process" and is not the best strategy for multiple reasons (unessecary rework, additional labor costs, as well as making the solder joint more brittle, [i

We are struggling with an effective way to control our SMT processes. I'm curious as to what parameters other companies monitor in their processes and how to control the quality coming off the end of the SMT line. We are currently restricted to a b

Looking at ideas for "best in class" process controls for SMT mfg. ops. Wanting to add improved p-controls at some of our suppliers and I'm looking at what others may or may not recommend. Already looking at the following: Solder Printing X-Y-Z axis

Dave, Yes the process is in control or that part that we can control. Visual inspection on first boards and then after a batch. I have had good prints with our current printing machines. My operators are very conscious of there work. Quality control

Morning guys, I would just like to find out which type of control charts / SPC type methods (if any) that people are using for SM and flow soldering. I am setting up process controls for our 3 flow solder machines at my new company and would just l
