Use of dosing needles in the electronics industry: Focus on consumables

In the electronics industry, the use of precise dispensing systems is crucial to ensure uniform and controlled application of adhesives, resins, and other materials. Dispensing needles are essential elements of this process, as they allow for optimal control of the flow rate and quantity of consumables applied to electronic components such as printed circuit boards (PCBs) . This article explores the types of consumables used with dispensing needles and their impact on the quality of finished products in the electronics industry.

Types of consumables for dosing needles

Dispensing needles are designed to be compatible with a wide variety of consumables used in the electronics industry. Here are some of the types of products commonly applied using these systems:

Glues and adhesives : Used to fix electronic components to PCBs or to assemble elements of small electronic devices, glues must be applied with great precision. Dosing needles allow millimeter control, ensuring that the glue is deposited only where it is needed.

Resins and coatings : Protective resins, such as epoxy resins , are used to coat printed circuits and protect components from external aggressions (humidity, dust, etc.). Dosing needles ensure uniform application, essential for effective protection.

Thermal Pastes : For applications requiring optimum heat dissipation, such as motherboards or cooling devices, thermal pastes must be applied precisely. The needles allow the exact amount of paste to be controlled, optimizing the thermal performance of the components.

Conductive Inks : In some applications, such as flexible circuits, conductive inks are applied using metering needles to create precise traces. These inks require a controlled flow rate to ensure electrical continuity and circuit reliability.
