The Characterization and Comparison of Spray Fluxers

Technical Library | 1999-04-26 11:52:34.0

An evaluation of two fluxers, one with a reciprocating ultrasonic head and the other with microjets, was performed using nine independent criteria. The paper describes the methods of testing and the results.

Case Study on the Validation of SAC305 and SnCu Based Solders in SMT, Wave and Hand-soldering at the Contract Assembler Level

Technical Library | 2007-11-15 15:54:44.0

At the contractor level once a product is required to be soldered with lead-free solders all the processes must be assessed as to insure the same quality a customer has been accustomed to with a Sn63Pb37 process is achieved. The reflow, wave soldering and hand assembly processes must all be optimized carefully to insure good joint formation as per the appropriate class of electronics with new solder alloys and often new fluxes.

Managing the transition on a global scale -- changing the cleaning agent means changes to equipment, processes, process control specifications and standards.

Technical Library | 1999-05-09 12:36:40.0

The production of electronics began with hand soldering, followed by manual cleaning, which reached its peak during the NASA program. Each step in the process tended to be considered on a stand alone basis, without thought being given to the preceding and following steps. Since each step had its own set of specifications, this led to a "patchwork" approach to overall quality.
