Silicone pressure sensitive adhesives protecting your electronics
Silicone pressure sensitive adhesives for masking tapes
High temperature silicone pressure sensitive adhesives for surface protection of consumer electronics and masking applications.
The idea of masking a component during a manufacturing process has evolved through the years, as parts become more intricate, smaller, and more complex. The temporary masking and protection has been used in various industries ranging from aerospace landing struts to the smallest connections on a circuit board, each application requiring the masking to survive higher temperatures, or more aggressive processes.
When looking for a safe and reliable solution to protect sensitive electronic components during processing, or masking of a fabricated object prior to powder coating or metalizing process, manufacturers will often use a silicone masking tape. Silicone masking tapes are self-wound adhesive films, typically coated onto a polyester or high temperature resistant Kapton polyamide film. The pressure sensitive adhesive used must be high temperature resistant and with outstanding adhesion even to irregular surfaces. They must adhere to low surface energy plastics, various circuit board materials, exotic metals, or survive chemically aggressive environments.
What are the key factors for silicone pressure sensitive adhesives for masking applications?
Silcolease™ Silicone Pressure Sensitive Adhesives (PSA) have all the key attributes tape engineers are seeking for:
- Adhesion to various substrates, with clean removability even after or during high temperature exposure
- Conformability to flow and adhere onto irregular surfaces and topographies, allowing for an excellent seal against aggressive chemical baths and environments
- Chemical resistance to survive solvent and chemical exposure, such as acid washing steps during printed circuit board (PCB) manufacturing, so that sensitive electronic components like PCB gold fingers remain clean and free from contamination
- Solder and metal coating resistance to survive PCB manufacturing steps
- A range of tack and adhesion to adjust for different application needs, without the worry of lift-off or flagging during processing.
- Adhesion stability at high temperature up to 270°C through most manufacturing processes, with no staining or tarnishing of the protected surfaces
