I would contact your PCB supplier, they usually have some type of software for panel optimization. Each shop potentially uses different size panels so it is a good idea to ask them what they are using and go from there. Keep in mind that there are

Yeh, the IPC courtyards are for old ladies. I want to say that at one time IPC was talking about a new set of rules. Maybe, 7351 - SMT Footprint Design Guidelines??? Anyhow, Jim Blankenhorn at SMTPlus [ sales@smtplus.com ] has done THE best job o

ricardof Unfortunately I cannot comment on many of your questions however I can lead you to one important article as to basic assembly optimization techniques to maximise throughput (or minimize assembly time, which is pretty much the same thing...)

Via in pad lets your layout guy run traces on inner layers so there's more more area available on the outer layers for placing parts, test point, etc. There are also electrical advantages due to shortening paths, but I'm just a simple mechanical eng

Hi, We're going to migrate our boards from through-hole to SMT, and I'm dealing with the PCB layout. I've found a lot of references for fiducial marks but none of them states if components can be placed beyond the marks limits or only within the are

I don'treally think anyone can give on answer on this one because we don't know what size the any thing is, or how many operators will be running, or where your parts are and the how you set up, if you need a staging area. There are just to maney wha

Hi rob, We use the component for a long time and never had a problem with the reflow process. Since the component is Leadfree we see the problems. We have the same problem with defferent pcb's. The tin not always flows to the same direction. I check

Dear James 1)Standby the part for next model. 2)during the convention period,replaced the part for the machines. 3)All the programme are following the CAD data.It's help to reduced the situation. 4)All the feeder must be in the good condition. 5)The

Approaches are: * PCDATAK sells [through distributors and hobbist sites] inexpensive layout software and plastic sheets that you run through a copier and then use to image the traces on the bare board. Since you have the software, all you need is th
