0207/0204/0102/1206/0805 are all not too bad. 0603 are also acceptable for those not so old. 0402 is a bit tough though but still manageable after a while. So anything not smaller than 0805 will be okay for most people. Maybe the problem is with the sourcing and cost of low SMD components in low quantity. The other problem is for SMD ceramic capacitors (generally no marking). Not many people will have a capacitance meter.

Subject: RE: [PIC] PIC prototype board comments? Anyone thought about doing LARGE surface mount as a way to keep bread boarding cost down? 1206 are REALLY not hard to solder. Neither are any of the SO... IC packages. And if you have an existing stock of through hole parts, you can always just bend the pins under or out and solder them down. Probably not going to happen, but I'd be interested in SMT bread boarding systems... Not much available in that area. --- James Newton, massmind.org Knowledge Archiver james@massmind.org 1-619-652-0593 fax:1-208-279-8767 -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
