You can get an used GSM1 for little money, used pneumatic feeders are cheap and reliable. Software is excellent and there's a lot of spares on the second-hand market. Initial investment is low and you get excellent machine, superbly built, that will

Martin It might be possible to mount a deballed BGA as you mount a QFN. Thinking about doing it, it could be a lot more difficult than first thought. When you heat a BGA, it 'dances' on the board because of the different CTE of the materials involved

Dave, A low residue/No residue flux does exist that when an excessive amount of flux is applied it would only create a cosmetic problem not a reliability issue. The active ingredients are neutralized by the heat applied in the soldering machine and

I measured the diference soldering the TC to the pad and just tape down it, because i had a trouble with accuracy of some TC's. For the TC's I just taped down, I used additional heat-conductive paste to make a a termal connection from the TC to the s

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

I'm looking for a handheld barcode scanner that will handle high resolution 1D and 2D symbologies. Some of our 1D codes are down to 3.3mil lines and your average scanner can't reliably scan that resolution. I've used PSC and Wasp equipment before b

Dan, If you are starting a library from scratch, it will probably take a while to program on any machine. Building a library is the most time consuming part. We use ViTechnology machines. They have a generic library that you could use to generate

I agree, setting a standard for the pcb fab shop is good. I use a fiducial a little smaller than the spec you mentioned, I use 30 instead of 40 mil, which is the minimum recommended for my machine. The rest of the spec (SMEMA Standard 3.1) appears th

I had 2 Contact 3AV and 2 Contact 3Z machines. Basically the same as 3AVX machines. Both models are good machines. They are perfect for small production and even medium production size lots if you have multiple machines. Super easy to operate and
