1. Solder and Flux
(1) Solder Paste
Use solder paste Sn:Pb=63:37wt%.
For your reference, we are using
63Sn/37Pb RMA9086 90-3-M18,
manufactured by Alpha Metals Japan Ltd.
96.5Sn/3.0Ag/0.5Cu M705-GRN360-K2-V,
manufactured by Senju Metal Industry Co., LTD for any
internal tests of this product.
(2) Flux
Use rosin type flux in the soldering process.
If the flux below is used, some problems might be
caused in the product characteristics and reliability.
Please do not use these types of flux.
