why do you bake them? Repeated bakes affect solderability. PCBs from a "good" supplier, stored in a temperature/humidity controlled plant, and used promptly do not require baking. Cheap PCBs stored in an unairconditioned warehouse at high temperature/humidity may require baking. If you do this, what is the actual cost savings???? ______________________________ Reply Separator _________________________________ Subject: assly:baking of hasl pcbs Author: [log in to unmask] at internet Date: 10/23/96 6:50 AM Date : 23/10/96 11:38 Msg From: PROCESS ENGINEERING hello is there any criterion for baking of HASL PCBs . actually as per customers guidelines we have to bake the HASL pcbs prior to their use in assembly line. kindly suggest any standard or general practice i.e. the temperature & the duration for which the pcbs should be baked. if baked pcbs are to be used after a gap of a day or a week, should they be baked again? or they can be stored in controlled envoirnment kindly comment regards nalin altos india limited e-mail<[log in to unmask]> e-mail<[log in to unmask]> *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * *************************************************************************** *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * ***************************************************************************
