- Solder Mask
As a trusted solder mask in Chennai is a protective coating that is applied to the surface of a printed circuit board. It covers the copper traces and leaves only the required soldering points. This layer plays a major role to protecting the board and ensuring accurate soldering. It acts as a barrier between copper and the surrounding environment in PCB manufacturing. It prevents oxidation and reduces the risk of short circuits. You will often see the green layer on a PCB. It is available in many colours and formulations depending on application needs. It is a standard requirement in professional PCB manufacturing from consumer electronics to industrial systems. When individuals discuss UV solder mask, they are typically discussing photoimageable solder masks, which are hardened by ultraviolet radiation. Reliable Spares & Consumables is one of the Solder Mask Manufacturers in Chennai. Our focus on provide quality products, which comply with the industry standards.
Why is Solder Mask Essential in PCB Manufacturing
Reliable Spares & Consumables is a Solder Mask Suppliers in Chennai We made it to protects both the electrical and mechanical integrity of a PCB. Without it, copper traces are exposed to air and moisture, which leads to corrosion over time. One of the main reasons is to prevent solder bridges. During soldering, especially in automated assembly, molten solder can easily flow between closely spaced pads. This creates unwanted electrical connections that cause circuit failure. This mask also improves insulation. It reduces the chance of short circuits caused by dust, debris, or accidental contact with conductive materials. This is especially important in compact and high-density PCB designs. Another key benefit is durability. PCBs often experience heat, humidity, and mechanical stress. These mask adds a protective layer that helps the board withstand these conditions. This increases the lifespan of the product and reduces maintenance costs. It guides solder to the correct locations, which is critical for surface-mount components and automated processes. This makes production faster and more dependable.
Producs Range Solder Mask
Chemask is a peelable masking compound used for wave soldering, conformal coating, or chemical processing, to safeguard specific portions of PCBs. Chemask is easy to apply, and it creates a protective, durable layer that prevents solder bridging and contamination. Chemask improves process control, decreases rework, and guarantees clean and precise outcomes in electronics manufacturing and assembly processes.
Seayu SMD Red Glue is a well-known adhesive that provides great bonding of SMD components on circuits boards. It has great adhesion, viscosity, and curing reliability. This red glue is also compatible with automated dispensing systems for easy application of adhesive to ensure placement of components and to provide steady adhesion. This is ideal for high precision and volume SMT production lines.
In surface mount technology, to help temporarily hold the added components for the wave soldering or double sided PCB assembly, SMD Red Glue, is high performance adhesive. It has a strong bond, thermal resistance and stable curing properties. This red glue is ideal for automated dispensing systems because it allows for the placement of components to be low, and helps with movement of components, thus improving assembly in electronic manufacturing processes.

Types of Solder Mask Used in PCBs
Different PCB applications require different mask types. Each type offers specific advantages depending on design complexity, budget, and manufacturing method.
-
Epoxy Liquid Solder Mask
Epoxy liquid mask is one of the oldest and most cost-effective options available. It is applied using a screen-printing process and cured using heat.
-
Liquid Photoimageable Solder Mask (LPI)
Liquid Photoimageable mask is the most widely used type in modern PCB manufacturing. It is applied as a liquid coating and exposed to UV light through a photomask.
-
Dry Film Photoimageable Solder Mask
Dry film mask comes in solid sheets that are laminated onto the PCB using heat and pressure. Like LPI, it is patterned using UV exposure.
-
Top and Bottom Side Masks
Most PCBs have solder mask applied to both the top and bottom sides. Each side may have different design requirements depending on component placement.

How to Use Solder Mask Properly
Surface Preparation Before Applying Solder Mask
The PCB surface must be clean and free from dust, oil, or residue before applying solder mask.
Peoples often use chemical cleaning or mechanical methods to prepare the surface. Proper preparation make sure that the mask bonds well to the copper and substrate.
Application and Curing Process
The application process depends on the type of solder mask used. Liquid masks are sprayed or coated evenly across the board. Dry film masks are laminated under controlled conditions.
Exposure to ultraviolet light defines the soldering areas. After exposure, the board is developed to remove unwanted mask material. Curing is the final step.
Common Mistakes to Avoid
Some common mistakes can affect the performance:
- Insufficient clearance around pads
- Incomplete curing
- Using unsuitable mask types for complex designs
Avoiding these issues requires accurate design files and close coordination with your PCB manufacturer.
Selling Popular Mask Colours
We offer many variety of colours to meet functional and aesthetic needs.
- Green
Green is the most common solder mask colour. It offers excellent contrast and visibility during inspection. It is also the most cost-effective option.
- Red, Blue, and Black
Red and blue are often chosen for branding or visual appeal. They are commonly used in consumer electronics and prototypes.
Black is used in specific applications where light reflection must be minimized. However, it can make inspection more difficult.
- White and Specialty
White is commonly used in LED boards because it reflects light efficiently. Specialty colours are available for custom projects but may increase cost.
We guide you in selecting the right colour based on application needs.
