Also Rehm Thermal Systems Ovens would be worth a look... They are well made, ALL stainless tunnel , 3 phase blowers, highly realiable, and they have new entry level series called VXC Series starting at 6 zones+, but based on same tech and build as t

Hello All.....wondering if anyone out there has needed to isolate a QFN ground pad from the device and how you may have gone about it. We are thinking about using a micro drill to remove the pad, but if anyone out there has a better idea I would be v

Mask the pad on the PWB using liquid solder mask. Cure the mask and away you go. Use a mini stencil and a squeegee to maintain planarity and minimize issues at paste print. We have used this technique before. In other cases we have masked the bott

We will try both the solder mask and the .001" Kapton and see where we end up with each. This is a fine pitch dual row QFN and we cannot afford too much paste on the .004" stencil we are using. We have experienced shorting in the past with .005" sten

We've used masking tape and peelable (pink) mask to mask our boards before conformal coating for a long, long time. This is a huge time sink, and increases our lead times (particularly because of the cure time for the pink mask). What are other com

Are you concerned with physical vibration or electronic interference? If you can see your morning coffee have "rings", screen printers may suffer. Trains are a monsterous source of electrical "noise", just by thier engine (electric and diesel) not

Hello all. I was hoping that maybe someone has a manual for a Omniflo 5. Build year is 1998. Photocopies would be greatly appreciated, and willing to pay. Even if we could put down a deposit, you send the manual we do the photocopy and we can send it
