BGAs and QFPs packaged in Trays are oriented with Pin 1 or corner A1 oriented towards the Pin 1 identifier on one corner of the Tray, which is usually identified by a chamfered corner. The Trays themselves are usually governed by JEDEC Registered Ou

Since I'm new to the forum I probably ask previously answered questions (that I have not found) but I would be grateful if someone could clarify this for me. I'm in R&D at a company where we design low volume (1k-10k) fairly complex PCBAs for our pr

Hello Everyone. We are setting up our first SMT line and are looking for recommendations on printers and reflow ovens. Currently most of our manufacturing is outsourced and we want the ability to manufacture all of our products in-house. One impor

I gather from your question that you might have experienced large scale system implementation problems in the past, or at least fear experiencing it in the future. This is a very valid concern based on the performance of traditional CIM systems. Fo

Hi Back later on this tread, yet I did want to slightly correct one thing DaveyF wrote. Again only slightly. Even at 90C, moisture does start to leave the board. Now it doesn't do it so well as above 100C at sea level atmospheric pressure, yet it s

I think I had my units wrong in my previous post - that blueprint job was 6 years ago and fading fast. My level of 700 would have the same units as Dave's level of 1000. This is the metric measurement of lux, vs the imperial footcandles. fc to lux

thanks everyone! When we have a PCB to do, for one component, they usually give us an excess of 10 components! We are issued over 2,000 components. Does that sound reasonable? The problem is usually when the head picks up the component before it r
