I agree with previous postings regarding print speed: Solder paste type/versus fine pitch. Question: Is this a double sided pcb with fairly easy component packages on both sides? In such case, consider make the panel like this: Every second pcb in

I think the first is a .1uF because it is being used as a charge pump cap on a max202cpe.

Ozzy, it is a 1uf cap, not a .1. The 5 indicates 5 zeros after the 1. The MAX-232ACPE uses .1 uf caps. You indicated that it was not the "A" version. phil.hopkins@apcc.com

We place parts like this with a contact systems machine (3Z). The part comes on a reel and has a flat top on it (as mentioned above) that can be removed as soom as it comes out of the oven.

Hi, It sounds like your a little new at profiling, and can be difficult to do well. We purchased a KIC profiler that has software that will take your profile data and tell you the best oven temperature settings and conveyer speed to use. You need

Why look at buying expensive equipement when you can have your board house multi-up a panel of boards for you. You just saved at least $150,000 American, didn't have to re-evaluate any solder paste, and even opened your process window on your oven.

Heck no, I mean we print relatively slower on complex boards, as in 1 inch/sec (25.4mm/sec), and maybe 2 inches/sec. (51mm/sec) on less complex boards. SMT is not a bottleneck in our plant and printing never the bottleneck in SMT, so I see no need t
