Good Morning Mark, I do not believe that you can group images from multiple cameras. You can save a camera image into the library but you would need to re-name the part number for the side camera if you have an image from the downward looking camera

The standard J-STD-033B.1 addresses how to store moisture sensitive components. A dry box is a good, convenient way to store MSDs, but there are other methods to consider which are outlined in the standard. Are you sure that the problems are caused

Are you absolutely sure the problem is with the humidity? We had a problem with 3528 size leds, damaged by the pick and place nozzle because a 0.2mm mistake in the height measurement. Also, we found that several suppliers are using fake desiccant ba

Hi , I think that our problem is humidity, because when I use leds from new tape ( pack in MBB ) no any defects.After that, we put opened tape in our store.After 2-3 weeks I use the same tape with leds, and we have 2-3% defective leds.I make this tes

Hi, It is very important to follow IPC JEDEC 33 specification for storage and handing of all MSDs. In many instances defects caused by excess moisture in packages is not immediately evident (pcbs may pass final test) but when pcb has been in the fiel

Hello everyone. I'm looking for some general information on reel counters. We are trying to tighten our inventory counts, and rather than estimate a reel we're looking into getting an accurate count via a reel counter. So first, I'm wondering what

Hello Rajeshwara, If not mistaken, the 25% solder void specification is for BGA...As I I as know, no specification given to mosfet component yet..I think you are right, I need to look at the stencil aperture in order to reduce the air trap underneat
