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

Thanks for the reply. We have software. It just won't connect when the Fuji controller (Flexa) is powered on. It appears that the controller ties up the GEM port. We were wondering if there is something that needs to be reconfigured or shutdown o

It depends how manual is the printer. you need to control pressure and speed. If you control both by hand, it is difficult to discuss results. If the pressure is controlled by the printer, than you should be able to do it by one deposit. Also is the

Our DEK248 started to behave oddly - squeegee speed can't be controller anymore. It always moves with max.speeed or something close to that, regardless of the current settings. Also, the table sometimes shoots out with very high speed. I am suspectin

The barbed fitting will work but you will lose all control over the speed of the cylinder. The air control flow valve is essentially the same as the barbed fitting but it allows the user to adjust the volume of air that is supplied to the cylinder wh

We keep all moisture sensitive parts in a humidity control enviroment at our main plant, but our return/refurb products building does not have humidity control. My question: Do moisture sensitive ICs that get hand placed by our refurb/return team n

Ensure you control the assembly completion. My previous experience, we control the assembly MUST be completed within 72 hrs, since you open the bare PCB seal, until you completed all the soldering process (Reflow & AWS). We manage to control the abo

You don't say what kind of printers you are running, but if you had multiple light sources and independent control of direct an oblique lighting (either manual and software controlled) usually pretty "do-able". I have customer doing almost exclusivel

Placement force can cause chip cracking-micro cracks also. As machines are getting faster they tend to not control force other than spring pressures and z displacements. There are some machines that have full closed loop place pressure control , but
