3PCS UV Solder Mask UV Light Curing Solder Mask Ink BGA, PCB Solder Resist Ink- Green INK BY WAIMILK

Description

Product Overview

The WAIMILK 3PCS UV Solder Mask is a professional-grade solution designed for precise PCB maintenance and repair. Each package contains 40 grams of vibrant green solder mask ink, formulated to provide excellent adhesion and insulation on copper substrates. The mask is compatible with high‑power UV curing lamps, delivering rapid polymerization that creates a durable, non‑conductive layer. With dimensions of 3.5 x 0.5 x 0.5 inches and a lightweight design of 3.17 ounces, the product is easy to handle and store. The formulation is fuel‑powered, ensuring consistent performance without the need for additional batteries. This mask is ideal for technicians, hobbyists, and engineers who require reliable protection for delicate electronic assemblies.

Usage

When repairing printed circuit boards, the UV solder mask is applied to areas where copper traces have been damaged, peeled, or where additional insulation is required. The mask works exceptionally well on smartphones, computers, and other electronic devices that rely on fine‑pitch circuitry. Users should first clean the PCB surface, apply a thin, even layer of the green ink, and then expose the area to a high‑intensity UV lamp for a few seconds. The rapid curing process ensures the mask bonds securely, preventing further oxidation or short‑circuit risks. After curing, the mask remains firmly attached, providing long‑term protection against moisture, dust, and mechanical wear. For best results, store any unused mask in a dark, sealed bag to preserve its photosensitivity.

FAQ

What type of UV lamp is recommended for curing this solder mask?

A high‑power UV lamp with a wavelength around 365 nm is ideal. The lamp should deliver sufficient intensity to fully polymerize the mask within a few seconds for optimal adhesion.

Can the mask be used on both copper and non‑copper surfaces?

While the formulation is optimized for copper, it can also adhere to other conductive surfaces after proper cleaning. For non‑copper substrates, ensure the surface is free of oils and contaminants before application.

How should I store leftover solder mask to maintain its effectiveness?

Keep any unused mask in its original sealed bag, away from light and heat. Storing it in a dark, cool place preserves its photosensitivity and prevents premature curing.

Is the mask safe for use on high‑frequency circuits?

Yes, the cured mask is non‑conductive and does not interfere with signal integrity, making it suitable for high‑frequency and RF applications when applied correctly.

What warranty does WAIMILK provide for this product?

WAIMILK offers a one‑year limited warranty covering manufacturing defects. Customers can contact support for replacement or troubleshooting assistance.
