PCB Developer Machine Introduction

The PCB developer machine is a crucial piece of equipment in the production of printed circuit boards (PCBs). It is used to remove the unexposed photosensitive layer (typically a dry film or liquid photoresist) from the PCB after exposure processing, revealing the circuit patterns that need to be etched or retained.

Working Principle

The PCB developer machine dissolves the unexposed photosensitive layer through spraying a developer solution (usually a weak alkaline solution). The exposed photosensitive layer undergoes a polymerization reaction with the developer solution and is retained, forming the desired circuit patterns.

Operation Process

1. Preparation: Place the PCB to be developed into the developer machine and prepare the appropriate developer solution.

2. Settings: Set the parameters of the developer machine according to the type and development requirements of the PCB, such as development time and temperature.

3. Start: Start the developer machine and begin spraying the developer solution. Ensure that the solution evenly covers the surface of the PCB.

4. Wait: Wait for the set development time to elapse.

5. Inspection: Remove the PCB and inspect the development results. If the requirements are met, proceed to the next step; if not, the PCB may need to be redeveloped or the development parameters may need to be adjusted.
