hi bill and thank's i want to pass an european test and also the UL test currently the board carry the power at 230vac and a section with triac handle 3-phase at 380 with neutral the card is used in a coffee machine. so in some part of the pcb there are some trace with 380vac and some with 230. actualy i have less space on the pcb and also i look for the possibility to cover all the board with a conformal coating also to protect from the steam and moisture. i use also connectors from JST series VH rated 250vac with 3.96mm pitch. and for the power stage JST series VL rated 600vac with 6.2mm pitch thank's ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8c ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TECHNET <your full name> To unsubscribe: SIGNOFF TECHNET ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
