Being an Electronics Technician is really challenging especially dealing with SMD (surface mount device) such as Spansion S29GL064 likewise the ST M29W640 TSOP48 NOR flash memory for Huawei Echolife BM622 4G WiMAX wireless broadband modem router CPE.
"Baklas Kabit" is really not a good option when removing the NOR flash memory if using the Rework Station hot air espeacially for SMD chips, excessive heat and air pointed by nozzle of the Rework Station will damage the TSOP48.
This option is an alternatively for repairing the Huawei BM622 without using the "Baklas Kabit" method, in other words if you have a new Spansion S29GL0640 or ST M29W640 after programming it and ready for soldering you can test if the chips is working or not to eliminate backward works.
