14,000 uf now that's a BAC!!! Your thinking is correct. Connecting capacitors together works just opposite to connecting resistors together. * Capacitors in parallel add like resistors in series [Ct = C1 + C2 + ... Cn]. * Capacitors in series add l

Industry-wide, there is no current requirement for baking of bare boards. It adds no value. * IPC-HDBK-001 has guidelines olden times. * IPC-TM-650 has several test methods to determine moisture resistance to both liquid immersion and absorption from

Wow - 11,000. We have 8K-9K, and we have had three people working on it for the last 6mos, around their other duties. We aren't done. Some MFR's changed PN's. Some add G, some add LF, some add NOPB, some add Z, Some add a "+", etc. Some have no d

Oooo, big bucks wusher!!! Consider the SMTnet Archives a valued resource. For instance, look at: http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=1632&mc=2 As far as your resistivity measurement is concerned, you hav

Hi Greg, why don�t you see it this way: How many parts get lost ( consider the type and packing (reel, stick, tray ))loading the machine or replacing it. - This is the amount you should add for each job. How many parts are rejected or discarded by th
