In that the machine times out and waits for a feeder refill and doesn't just skip that part and leave the space empty, it's not a defect. I have found 500ppm *fairly* easily attained in SMT depending on the board mix and how you define (1) a defect,

From my understanding: Sigma is the same as one standard deviation. So 3 sigma is the same as 3 standard deviations. It all boils down to how repeatable your machine is. Another way to look at it is the probability (or confidence) that the machin

My chipshooter will not "Time out", it will try to pick 3x and then alert the operator. Which would be 3 misses per empty reel. Unless I misread his post, he said 500 ppm at the placement machine. That makes a big difference.

I always look at the support structure. This is where I feel the real Dollars and cents come into play. Sure you can calculate the derated value over months or years. But If your machine is in a "machine down" situation the derated value does not cha

Contributors in order of importance: 1. PCB design - if you have large thermal pads, a grid of via holes should be created. Components with low profile will not let the gas to escape from the joint. The only way is going down. 2. Reduce paste volum

Crishan, Do you check the Nozzle orientation? some machine use a Rectangular o circle nozzle body, and this reduce the vaccum. When this component is taked from the feeder and the camara measured recognized the pins? Do you change the type of rec

During the electronics manufacturing industry downturn in 2000,2001,and 2002, a very high amount of manufacturing capacity was shut down in North America and moved to Asia, mainly China. I'm interested in knowing how many SMT placement machines (u

I bought a YV100XG machine with AutoTC (Automatic Tray Feeder), Everything is working except AutoTC, when I active this function, pops up the error that the Servo Motor LZ1 was not found. I changed the control card of the servo motor, checked the wir

The machine had the Auto Tray installed but was removed to put here in the company because the machine was bigger than my elevator. The owner told me it was working, which made me waste time testing all possible settings, electronic cards and cables.

Dear Sr.Tech, We tried to adjust the soak time and TAL time of reflow profile, but it doesn’t seem to help much.
