13. Notice
13.1. Soldering
(1) Flux, Solder
· Rosin-based flux should be used.
Do not use strong acidic flux with halide content exceeding 0.2(wt)% (chlorine conversion value.)
· Use Sn-3.0Ag-0.5Cu solder.
(2) Standard flow soldering profile.
Solder Temperature Soldering Time
250 ~ 260 °C 4 ~ 6 s
(3) Resistance to soldering iron goes in the following condition that tip temperature is 350 °C max, and
soldering time is 5 s max.
(4) Products and the leads should not be subjected to any mechanical stress during soldering process.
(and also while subjected to the equivalent high temperature.)
13.2. Cleaning conditions
Products shall be cleaned on the following conditions.
(1) Cleaning temperature shall be limited to 60°C max.(40°C max for IPA.)
(2) Ultrasonic cleaning shall comply with the following conditions with avoiding the resonance
phenomenon at the mounted products and P.C.B.
