阳光电源逆变器生产工艺流程

English Answer：

1. Raw Material Inspection:

All incoming raw materials undergo rigorous inspection

to ensure they meet specified quality standards. This

includes visual inspection, dimensional verification, and

testing of electrical properties.

2. Component Preparation:

Electronic components are sorted, counted, and prepared

for assembly. This involves lead trimming, bending, and

tinning to facilitate soldering.

3. Printed Circuit Board (PCB) Assembly:

Surface-mount technology (SMT) machines place

electronic components onto PCBs with precision. Automated

optical inspection (AOI) verifies component placement and

solder joints.

4. Soldering Process:

PCBs are passed through a reflow oven, where molten

solder melts and forms electrical connections between

components.

5. Component Insertion:

Through-hole components are manually or mechanically

inserted into PCBs and soldered in place.

6. Transformer Winding:

Copper wires are wound around laminated steel cores to

create transformers, which are essential for power

conversion.

7. Assembly of Subassemblies:
