Outside the MSD issues stated already (and I cannot provide a exact time not knowing multiple factors like Humidity levels, temps, exposure times, etc...) OSP might be the very worst finish to use in this scenario of side 1 / store on a shelf / side

Hello, I have a problem with the solder paste process, I need a solder paste with no Start-up Time because We do not work 24 hours in the manufacturing process, we works only 8 hours a day and at the finish we need to store the paste in the refr

Hi all, kindly asking for some hint with a problem we encounter with our SPI: After inspection, the SPI should show the defect details, but it doesn't. I can see the files created by the realtime-card in the exchange-directory between windows- and

I checked the spec sheet and it gives pressure and no volume. The volume on one of my older Yamaha's was about 2.7 CFM. That corresponds roughly to the volume of a small 2HP compressor at your local hardware store. You can place on of these in a smal

Hmmm.... When I clean my stencils after I run a job, it is to clean the paste off the stencil so it doesn't dry out in the apertures and on the stencil surface while it is being stored. Wiping the stencils during production is to clear the paste of

Hello, I have to learn how to program an old MyData (M9) pick and place machine that's been sitting in the company's basement for several years. Unfortunately, I have very little documentation. The machine runs, and there are some programs stored

I agree with you. I just said, if it is customer requirement, factory has to implement it, right? :) Of course it is huge amount of money. SPI is the main control, but it doesnt save you the pressure, speed, snap of from the printer to the trace (us

Has anyone else been experiencing this lately? We have had a rash of boards that come in properly vacuum sealed. We store them in the hot room until we are ready to build, and we get bubbles under the solder mask. We've had 4 different jobs, all di

Someone with some more definitive knowledge of these machines will no doubt chime in at some point, but my thought was that the "A-table" is just a data table that stores I/O information. Thus, being "off in A-table YV100X:N2323 YV100XT:n2223" just m

It seems there isn't right connection between solder and solder-legs. Maybe check that the LEDs get huminidity, have some oxidation on the legs, try different solder paste, check the reflow solder profile. On the photo I can not saw properly reflowe
