About lead free solder (PbF)
Caution:
CAUTION
Distinction of PbF PCB: PCBs (manufactured) using lead free solder will have a PbF stamp on the PCB.
- Pb free solder will tend to splash when heated too high (about 600*C).
- Pb free solder has a higher melting point than standard solder; Typically the melting point is 30 40*C higher. Please use a high temperature soldering iron: In case of the soldering iron with temperature control; please set it to 370 + 10 C.
DANGER OF HIGH VOLTAGE AND HIGH TEMPERATURE (HOTILIVE) OF THE INVERTER POWER SUPPLY (U)
INVERTER WARNING
This Inverter board looks like a regular PCB. However, this PCB drives the magnetron tube with extremely high voltage and high current. Improper handling can result in an electrical shock or burns, which might lead to injury or death.
- IT HAS: 1 high voltage and high current circuits. It functions the same as the high voltage transformer and high voltage capacitor in ordinary microwave ovens. Very
- Very high voltage which may remain in circuitry even when oven is off. High voltage charge may remain in the capacitors on the board.
DO NOT:
- Aluminum heat sink that is energized with very high voltage and high heat energy.
- 1 care should be taken to avoid possible electric shock hazards. High voltage charge may remain in circuits.
- Do not touch aluminum heat sink because it is energized with very high voltage and is also very hot in high heat energy.
- Do not try to adjust or tamper with preset control on the Inverter board because it is very dangerous to adjust without proper test equipment.
- Do not test oven while Inverter grounding plate or screws are loose. It is very dangerous to operate H.V. Inverter Circuit (U) with loose mounting screws or if improperly grounded.
