Brad- The Spec can be downloaded free from IPC at http://www.smema.org/smema1.2.pdf (or IPC.org search for SMEMA Standards). As per Conveyor edge clearance should be .187" or 4.7mm. Regards, Cal Communications Test Design, Inc. www.ctdi.com

There's no easy answer. It depends on: * Thickness and size of the PCB in the array. * Means of separation. * Type of component. SMT components are more sensitive to the forces that need to be applied to separate the PCB. * Type SMT device. Ceram

What is the ideal component edge to board scored edge clearance?

I was wondering if anybody could tell me what a good clearance would be for board designs to allow for the use of inline equipment? My company currently runs a batch line but I want to make sure we are designing properly for inline if the need arises

Generally, a well-designed assembly should not require man-handling of the PCB to the point where it is deflecting like this. Is the housing too small? What kind of clearance do you have and is there anything you can do to alleviate the issue (clos

80% on edge pads and >60% on center pad(s). So with this in mind the component body should stand off a bit.

IPC-A-610F 10.2.6 Laminate Conditions - Depanelization talks to the acceptability of the depanelization criteria for assembled boards. There is no requirement for moisture sealing with epoxy or other material. Basically, the standard requires that th

We use a FKN pizza cutter and found that even with 5mm clearance and the proper orientation of the part larger ceramic capacitors 1812, 1210 would still stress fracture. We have successfully fixed stress fracture problems by adding routed relief slot

Stuart, My suggestion is a DFM meeting (most of the process people dream about a meeting like this, and luckily, I've been to a few) with: - project manager (if there's one) - customer service rep (annual volume, lot size, product life) - smt proce
