PCB Developer Defoamer Selection Guide: Chemi Tech Solutions

In PCB manufacturing, foam control during the developer stage directly impacts line precision and production efficiency. Excessive foam may cause uneven chemical distribution, equipment overflow, or residual defects. Chemi Tech specializes in defoamer R&D, offering PCB developer-specific defoamers formulated to rapidly collapse foam and suppress reformation, compatible with both alkaline and mild acidic developer systems.  

Key Features:  

1. Instant Defoaming: Low dosage achieves immediate foam collapse, suitable for high-speed spray developers;  

2. Chemical Stability: Compatible with developer solutions without affecting active ingredients;  

3. Long-Lasting Inhibition: Minimizes foam recurrence, reducing downtime for cleaning;  

4. Broad Adaptability: Effective for HDI and multilayer board developer processes.  

Chemi Tech’s defoamers utilize optimized molecular structures to prevent substrate residue, ensuring no interference with subsequent etching or plating. Users can select models tailored to developer chemistries (e.g., sodium carbonate or KOH systems) for precise process integration.
