Hi, I've had some trouble with one of my GSM cameras. Its a 1 mil camera (in circular housing). Some components have fallen down the gap between the glass cover and the LED array closest to the rails. One of the resistors (closest to the left) has b

Thanks guys! Very helpfull info. SWAG, the manufacturer states that this material can withstand up to 350 Celsius for a short time period (around 10-20 seconds). It is my understanding that Durostone absorbs heat very very slowly like ceramic thus

I would suggest checking the feeder, MVF and MSR are both turret type and dont have the capability auto pik adjust in y. Y offset pick up would lead to : 1. Over turn component. 2. Missing component. Turret sequence is pick, recognize an

OK... My problem with BTUs is that they are getting stopped up because the flux is not going from vapor form to liquid form; instead it is crystalizing (looks like a blizzard took place in the flux box and chiller boxes) and clogging up the flux box,

I like this definition the best. After years of sales of pick and place and other, this is always still a topic of discussion. If your customer's cycle time involves building a board in two different machines, then I would suggest measuring and add

I am always looking for ways to make my boards more reliable and easier to fabricate and assemble. I have been baselining my footprints off of IPC-7351 and with the latest revision of the calculator they have started a new feature. Normally on say

The dumbest thing I read was the response to me saying people should not automatically send product to China. I was told not to bury my head in the sand. A lot of companies are being lemmings and taking it for granted it's best to send a product to C

We are looking at replacing our aging 4790 for something. We are replacing our GSM1 with an Advantis. We are a prototype shop and do runs of 5 to 30 normally and once in a while a run of 300. So we are looking for flexibility and ease of set up.

Immersion Silver, ImAg, is becoming the finish of preference. This is due to it having similar process limits vs. SnPb HASL. There were some early concerns about shelf life, but new chemistries have extended finish shelf life to 12 months+. Many boar
