Ensure superior quality in your PCB fabrication line with our essential Green Oil Vacuum Degassing and Quiescent Chamber drawing. This free MechStream download is a critical resource for process engineers and technicians in electronics manufacturing. “Green oil,” the common term for solder mask, is a vital layer, but trapped air bubbles can cause catastrophic defects like pinholes, poor adhesion, and incomplete coverage during the screen-printing and curing process.

This design provides a complete, fabrication-ready blueprint for a chamber that solves this exact problem. The unit is engineered to hold the green oil under a deep vacuum in a “quiescent” (still) state. This process effectively pulls all dissolved air and micro-bubbles from the ink before it’s applied. This pre-treatment step is essential for high-yield, high-reliability PCB production, ensuring a perfectly smooth, bubble-free solder mask application every time.

Our drawing package saves you from the complex R&D of building a vacuum-safe, chemically compatible system. Available in DWG, DXF, and PDF formats, these fully editable files allow you to build a professional-grade unit tailored to your production volume.
