Morning all, Can anyone recommend a simple low cost method to spray apply conformal coating to our PCB's. Looking for something simple, semi-automatic, and repeatable for operators to use without problems. This is a very low volume application, appro

Good morning. We have a used Nordson Coater, Batch type (not pass thru), w/o cure oven,that you can purchase for $9,950.00. Unit has been cleaned and lines purged. It was running when decommissioned, and is still in nice shape. Thanks, Nick Haviland.

after we teach their positions We tape the sticks down. It is also helpful to make sure that you tighten the "discs" that are located on the tension rods. There are available if you desire guides and stops from Samsung that attach directly to the fe

We know SIR coupons are not ROSE coupons, but coupon boards are: * IPC-B-24 (copper and HASL, FR-4 and polyimide) * IPC-B-36 (bare copper and HASL, FR-4 and polyimide) * IPC Phoenix board (bare copper, FR-4) * IPC-B-25A (FR-4, bare copper only)

We use a Yamaha YV100XT pick and place machine, we have just discovered this new error, during operation or resetting after making some changes on production data the machines freezes and the keyboard and controller freezed. to get it back to working

If there has general standard to guide which type of component can not be cleaned ? No-clean flux be used in solder process ,and the PCBA we build be subject to the filed of high frequence (13.56MHz). Is it very critical if the coating that adhered

Dear Chris Thank you so much for the prompt reply and it really helps. Do you have any SMT experience for rig-flex boards? Can you share with me about the differences with that of rigid boards? Is there any special precaution needed? When you were d

Yes, we have an SOP on how to measure. Basically, calibrate the measuring device and measure tension on the 4 sides and one at the center of the stencil. All measurement should be within 30 ~ 50 N/cm otherwise we will not use it and return it to sten

Dear all, The problematic IC being X-rays and shown excellent wetting with no solder voids. Meanwhile the samples to be sent for independent party to verify the failure, e.g. using SAM method. The condition of failure is the PCB assembly fail functi
