I think you needed an IPC Class 3 annular ring because for very dense designs, the smaller the annular ring the better, as less space is taken by the pad or via and more space can be dedicated to routing the traces in highly populated areas of the bo

| We've noticed that there are many different recommendations for pad sizes for various SMT parts. This seems to vary wildly from manufacturer to manufacturer for the same case sizes. Is there any standards that can used used to specify these sizes

I'm sorry, Dave - I didn't make myself very clear. Yes, this space (not really a "gap") is filled with solid solder. For instance, if you place a gull-wing component in solder paste, after reflow, there will probably be a thin film of solidied solder

Subtle spamvertising there. Lower Cost small machine brands worth looking at are probably: Mechatronic Intelligent Drives (UK only?) TWS Autotronik or their Manncorp branded models in the USA Fritsch Innotech Heeb (a virtually invisible market share

If I am putting chip capacitors on a .063 FR4 board, what size package should we stay away from to avoid cracking? If I use 2 mil copper on the outside layers of a PCB, am I limited to what pitch of parts I can use? Specifically, will using 0603

We don't have a gap between the lead and the pad after a SM joint is soldered. On our boards, this space is filled with the solder intended to attach the component to the board. How high do components sit above the surface of a board? Most people a
