(The position of the two Temp-sensor when soldering the south/north board)

1、Inspect the machine and then open it

(1) Check if the connection wire of the lamp body, the Temp-sensor and power cable is ok.

(2) Turn on the power switch. Allow the T-870A Power-On-Self-Test (POST) to complete. After this, Temperature set-points will display last value used.

(3) The front panel has two switches, controls the preheating dish and the infra-red lamp body separately;

2、PC Board Component Removal and Replacement

(1) Placed the PCB Board

Put the PCB board on the PCB board holder”, rotate the holder fasten nut”, fasten it. Move the PCB board holder” to choose the right position.

(2)the Process of unsoldering and repairing

①Adjust the position of the PCB board, make the chip at the centre of the lamp light. Adjust the height of the lamp body, keep the lamp 20-30mm from the chip.

②Put the temp-sensor at the edge of the chip, lay a bed of solder flux around the chip and on the temp-sensor, it will make the measured temperature more accurately, at the same time the solder flux will make the soldering chip more perfect, and keep the bonding pad away from conglutinating and having tin wool.

③According to the producing technological requirement or the size of PCB board, adjust the pre-heat dish temperature(adjustable 60-200℃).

When there is waterproof solid sealing compound on the chip,
