manual stencil print 2 passes

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

DEK248 schematic

Electronics Forum | Sat Jan 15 16:33:13 EST 2011 | dilogic

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

Moisture sensitive ICs in repairs/refurb

Electronics Forum | Thu Jun 06 10:08:55 EDT 2013 | grauen06

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

Cracked Capacitors - Analysis

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

Siemens Siplace 80S15 causing Line Controller to hang up, and 80S15 keeps waiting for machine data from Line controller

Thank you for your reply. So the machine should preform a zero set without the line controller being turned ON? I never tried starting the machine first so I am unfamiliar with this. Thank you again. This community is great. Sincerely, Katrina

There is too much variation in the different Conformal Coating types and application requirements that you will get many different answers. Your controls will be tailored to the job requirements. My controls for parylene coating aerospace product is

Width control on Universal Genesis (PWC) issue

Electronics Forum | Sun Sep 18 00:46:20 EDT 2022 | poly

This may sound silly but... I'm not sure where the glass scale is for the width axis. There is a Heidenhain rod 1020 rotary encoder connected to the motor that moves the width control, but I can't see any linear encoder / scale. I've given everything
