Technet, We have assembled SMT discrete components with solder peaks. Similar to those seen on PTH leads. There is an IPC spec for max. height of a peak for PTH leads of 1.5 mm (I'm pretty sure). Does anyone know of any such allowance for SMT devices? We're building to class 3 spec. and I'm leaning towards not accepting assemblies with these peaks as they were likely hand soldered in place. --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
