Masking plays a critical role in the conformal coating process, safeguarding components from unintended coating while ensuring connectivity. However, it brings forth challenges that impede efficiency and increase costs. In this article, we delve into the challenges faced in masking during conformal coating and present effective solutions to address them, optimizing the coating process for enhanced productivity and cost-effectiveness.
1/ The functions of temporary masking in conformal coating
Temporary masking is a crucial step in the selective conformal coating process to protect some unwanted components to be coated or cover connectors to ensure the high insulation of coating material could not block the connectivity. Commonly, manufacturers use masking tape, which is the most economical and simple to use product, or UV maskant supporting complicated masking areas with a short cycle time process.
‘Through successful research and testing initiatives, Prostech’s technical team has provided suitable temporary masking materials to address the challenges encountered in various manufacturing processes across different industries. Contact us promptly and access this article to explore detailed solutions for temporary masking.’
2/ Some common challenges of temporary masking
a/ Time consuming
Surely, using temporary masking requires 2 more steps of applying and removing, which increase the cycle time of a product. Especially in high-volume production, this can significantly slow down productivity.
b/ Increasing product cost (labor, material)
Assuming the process is automated, it also requires at least 2 operators to apply and remove the maskant/ tape, whereas it requires even more than 2- or 3-times laborers to handle in manual process. Indeed, the cost of temporary masking will add up to the end-product cost, which impacts the overall cost-effectiveness of the process.
c/ Risk of damage and contamination
One common concern of many manufacturers is the residue of masking material (residue of adhesive due to not fully cured, residue of tapes because of melting under high temperature…) which can interfere with electrical performance or long-term reliability. Cleaning off these residues can add additional steps and costs to the process. Also, during the removal of temporary masking, there might be a risk of damaging sensitive components, resulting in an increase of rework or replacement.
3/ Coating solution of Prostech to minimize these challenges above
To address the drawbacks of using masking materials in the coating process, Prostech offers a product line that eliminates the need for masking, featuring lightweight and thin coating layers capable of meeting various protection requirements:
- Non-masking requires without blocking the connectivity of the connector
– This solution allows the application of protective layers without the need for temporary masking materials or tapes, reducing the two-step process of application and removal of masking, thereby minimizing labor time and costs.
– Products can be applied directly to the surface without obstructing connectors, enhancing flexibility and saving time in the manufacturing process.
- Hydrophobic and oleophobic
Products will be easier to clean after use because residues or excess oil and grease will not adhere to the surface, reducing time and costs for cleaning and maintenance
- Fast process: 5s dipping, can be handled in under minutes
– The fast process allows for efficient application and removal of protection, reducing waiting time and enhancing production efficiency.
– Additionally, the short processing time reduces the risk of damage or contamination from prolonged contact with protective materials.
- Nano-scale to ultrathin scale.
– Thin and lightweight protective layers minimize the impact on the size and weight of the product, without increasing transportation and storage costs.
– Moreover, this lightweight nature does not affect the connectivity and operation of electronic components, enhancing flexibility and product performance.
