Importance of Precision in Electronic Manufacturing

Precision is key in the electronics manufacturing industry when creating consistent, high quality components. Dealing with contaminants, weak solder joints, or a lack of coating can cause damage to parts, leading to an increase in scrap waste and a bottleneck for production lines. Using the appropriate tools such as spray tech for the electronic industry and abiding by strict specifications ensures that every electronic device and component can be safely used to its optimal potential.

Sectors in the Electronic Industry Employing Spray Technology

Various electronic industries use spray nozzles to perform different functions. Each nozzle is carefully designed to handle a wide range of liquids at different low and high pressures as well as compressed air and gases. Our nozzles provide different spray patterns depending on the application.

PCB Cleaning and Surface Preparation

Printed circuit boards (PCBs) must be clean of all contaminants after sawing and before the components are attached. Spray nozzles use cleaning agents along the wafers as well as perform the microetch step by removing oxides.

Conformal Coating and Encapsulation

To seal the electronic surface of a PCB or PCBA, spray nozzles apply protective resin coatings. These resin coatings are evenly applied due to our anti-clogging spray nozzle design to ensure every surface area becomes encapsulated.

Semiconductor Manufacturing

Spray nozzles are used in various stages of semiconductor production, such as rinsing, cutting, etching, developing, and resist stripping. Spray nozzles are also deployed in clean room chambers to remove contaminants from footwear and other personal protective equipment.

LCD and Display Panel Production

Spray nozzles can be used for etching and cleaning when creating LCD and display panels. They are also used in clean rooms to decontaminate workers before entering and existing the production floor.

Common Nozzle Applications in the Electronics Industry

Blow-Off/Air Dust

Due to cutting and grinding processes, particles can become airborne to settle onto electronics. Spray nozzles can use a short burst of air to blow off electronic surfaces and PCB boards before the parts move to the next phase of production.

Flux Coating for Soldering

Spray tech in the electronic industry can apply a flux coating to surfaces. This flux coating removes the oxide layer for better solder wetting.

Acid Coatings for Etching

Spray nozzles can safely apply etchant (acid) to remove unwanted material layers during wafer fabrication. This provides more precise control and ensures better accuracy.

Humidification Control

Electrostatic discharge is a serious problem in the electronics industry during manufacturing processes. Spray technology allows for more concise humidity control by adding the appropriate amount of water into the air.

Rain Simulation Testing

Spray nozzles used in rain simulation testing create an environment where electronics are exposed to moisture during transit, storage, or operation.

Advanced Spray Systems for the Electronic Industry

Our advanced spray systems offer anti-clogging designs to prevent inconsistent flow rates while providing an even distribution of water droplets. We use high quality materials that can handle various liquids, chemicals, and strong acids to prevent corrosion of nozzle parts. Customers can take advantage of the quick release cap and adjustable spray direction to target the desired surface.
