Hi all Need advise. This has happenned twice in the last 2 months. The battery leaked all over the card (S-M - CNC 45 card no. 45.01.02.3) The m/cs did not start the next day. If the card is powered after a few years of storage the battery starts leaking and within a few days it is all over the PCB. We removed the chips and cleaned in Hot water / air agitn and againa nd again. Baked bare card and reloaded chips. NADA. Solvent extarct of bare PCB all perfect. Advise if we should change all chips - some TTL, some cmos, memory, eproms, etc. Anil Micro Interconnexion Pvt. Ltd D3-12 A, Corlim Ind.
