I am currently working on a manufacturing flow where some PCBA are processed with reflow oven (after being baked before processing), then cleaned with bath, then passed into contaminometer, passed into AOI. The point is after all of this, if AOI dete

How far from apertures is the label supposed to go? I'd say 1 inch is plenty. 3/4 inch might be plenty also. Do you have the ability to measure paste height? I'd say place the label on one board and print two. Is there an appreciable differenc

Thank you for sharing the helpful information. Let's say the PCB is a double-side assemble process and this PCB has completed the first reflowing SMT assembly process, is there any concern if the board is kept on the production floor with temperatur

Wanted to ask the SMT community if anyone has data on baking Clariant Desi Pak for 16 hours at 245 F. How are you cooling to avoid condensation reforming? Have you measured efficacy of desiccant after baked 10 times? 100 times 1000 times? 5000 t

While IPC-A-610 [ https://www.ipc.org/TOC/IPC-A-610G.pdf ] is a good starting point for establishing your inspection requirements, there is no requirement for using a specific tool to make a measurement. You need to choose the microscope, AOI, loop,

Good morning everybody Our PCB's keep on getting stuck on their way from the Printer to the SPI. That happens like between every 20 to 30 minutes. We've checked the conveyor with, the cleaning cycle and also the transport acceleration speed but none

Next step trace the RS232 cable. Check all output voltages on your power supplys, b oth loaded an d unloaded. Note any differences. Check he impedancesa of your loads ie is your 24 volt load only measuring a few ohms. You may have a short? sarason

If you decide on an epoxy floor, make sure you use a contractor that is experienced with installing ESD epoxy floors. The epoxy needs to be continuously mixed to keep the media consistent throughout. We had a contractor who failed to do that, and wh

Hi Dima, A past job used a PSE 300 from KOLB for 10 years. With proper maintenance, no problems were found. DST InJet was used in another production. As far as I know, there were no problems either. DST also has an interesting option, such as measuri

Dima, we just purchased an Aqueuous stencil washer. We already have a board washer from them and have been thoroughly impressed by their performance, also measures the resistance in the rinse water to confirm it meets the cleanliness standard you set
