3. Soldering
4. Cleaning
Clean the block Type EMIFILr(Lead Type) in the following
conditions.
(1) Cleaning temperature should be limited to 60°C max.
(40°C max for alcohol type cleaner).
(2) Ultrasonic cleaning should comply with the following
conditions, avoiding the resonance phenomenon at the
mounted products and P.C.B.
Power: 20W/liter max.
Frequency: 28 to 40kHz
Time: 5 min. max.
(3) Cleaner
(a) Alcohol type cleaner
Isopropyl alcohol (IPA)
(b) Aqueous agent
Pine Alpha ST-100S
(4) There should be no residual flux or residual cleaner left
after cleaning.
In the case of using aqueous agent, products should be
dried completely after rinsing with de-ionized water in
order to remove the cleaner.
(5) The surface of products may become dirty after cleaning,
but there is no deterioration on mechanical, electrical
characteristics and reliability.
(6) Other cleaning: Please contact us.
(1) Use Sn-3.0Ag-0.5Cu solder.
(2) Use Rosin-based flux. Do not use strong acidic flux with
halide content exceeding 0.2wt% (chlorine conversion
value).
(3) Products and the leads should not be subjected to any
mechanical stress during the soldering process, or while
subjected to the equivalent high temperatures.
