Electronic component adhesives provide the foundation to securely adhere discrete devices to various substrates. While commonly utilized for surface mounting parts onto printed circuit boards (PCBs), adhesives also serve a multitude of other uses including potting/encapsulation/substrate assembly/electronic repairs/potting applications and repairs to electronic systems.

This guide presents everything design engineers should know when selecting electronic component adhesives.

RW’s extensive and quality-tested database of 3500 adhesive materials offers electronic component adhesives designed specifically to meet design engineers’ requirements. In addition to technical data and key specifications, there’s best practices information, comparable materials as well as test method info on numerous material properties and data points – everything a design engineer could ever need!

Introduction

Electronic component adhesives can either replace soldering altogether or act in tandem with it to securely bond parts together. Some electronic component glues can act as electrical insulators while others conduct electricity through them; similarly, certain products provide thermal insulation while others conduct it away through thermal conduction channels.

Design engineers should carefully consider both thermal and electrical performance when developing bonding materials for electronics used outdoors, the environmental conditions surrounding their application and any specific application-specific requirements – for instance, electronic component adhesives used outdoors must withstand sunlight.

Adhesive chemistry plays an essential role in product selection. Epoxies provide strong bonds and excellent chemical resistance. Silicones combine flexibility with excellent high temperature resistance; acrylics resist vibrations and thermal cycling, and polyurethanes offer strong yet flexible bonds.

One and two part products for these chemistries are both available, enabling rapid curing through light, heat or room temperature – or in an automated dual curing process – and with automated dispensing capabilities offering greater speed and precision than manual methods of application.

RW offers eight categories for electronic component adhesives to make product searching simple online: These categories include Printed Circuit Boards (PCBs), amplifiers, chip on Board (COB), coils, connectors and ruggedizedizing for sensors.

Within each category, you can search products based on specific technical characteristics like curing time, bond strength, material resistance, conductivity or conductivity – making your search experience more tailored than ever!

PCB Adhesives

Printed Circuit Board (PCB) adhesives are integral in the assembly of printed circuit boards. They secure surface-mounted components like resistors, capacitors, integrated circuits (ICs), resistors to boards made of material like metal, plastics ceramics or glass; often connecting dissimilar materials together such as an aluminum electrolytic capacitor to polyimide or FR-4 substrate substrate.

Some PCB adhesives contain metal particles to provide electrical conductivity and EMI shielding. Design engineers looking for high temperature applications may opt for thermally-conductive PCB adhesives which dissipate heat instead. Furthermore, there are adhesives on the market which offer both electrical conductivity and thermal conductivity properties in one go.

Other products available from PCB adhesive suppliers are staking adhesives which support component leads and can withstand vibration. Staking adhesives also serve to replace mechanical attachments like fasteners while supporting lightweighting initiatives and lightweighting initiatives.

Applications for PCB adhesives may include bonding surface-mounted devices (SMDs) to PCBs; staking component leads; replacing solder or mechanical fasteners with fasteners and improving electrical conductivity – along with supporting lightweighting initiatives and supporting lightweighting initiatives. nettoyage
