[2] for pmfp packages hot bar soldering or manual soldering is suitable. table 9: suitability of through-hole mount ic packages for dipping and wave soldering methods package soldering method dipping wave cpga, hcpga - suitable dbs, dip, hdip, rdbs, sdip, sil suitable suitable [1] pmfp [2] - not suitable
