Masking Methods & Materials
Select the right mix of tapes, dots, boots, and liquid latex to protect connectors, fasteners, test points, and edge keep-outs. Balance removal time, residue risk, and cycle time to improve first-pass yield.
- Barrier vs shielding approaches, and when to combine both.
- Adhesion, residue, and temperature compatibility checks.
- Release methods that avoid fibre transfer or pad lift.
Designing Effective PCB Masking Strategies
Firstly, define keep-out zones early. Next, plan masking layouts alongside fixture design and coating paths. Additionally, ensure good access for operators, smooth nozzle movement, and proper purge capture during spray, dip, selective, or Parylene application. As a result, this alignment reduces rework and keeps production flow stable.
- Plan barrier lines and edge breaks around tall parts.
- Build “golden board” references and release checklists.
- Validate under-component wicking and meniscus behaviour.
Reusable Masking Boots
Use reusable silicone boots to speed setup, reduce consumables, and improve repeatability. In selective coating, boots often provide shield-type protection; with latex, they can form full barriers.
- When to prefer boots vs dots/tapes for connectors and headers.
- Design for heat, solvent, and chemical compatibility.
- Cleaning, inspection, and life-cycle tracking for boots.
Liquid Latex & Hybrid Barrier Systems
Combine masking tapes / dots with liquid latex to seal edges, via’s, and irregular geometries. This hybrid approach converts shield-type masks into true barriers, cutting leakage and edge creep.
- Latex selection, cure windows, and removal methods.
- Edge-seal techniques for grounding holes and fasteners.
- Defect prevention: de-wetting, residue, and fibre control.
