2015年4月15日 · 以工作熊在電子組裝廠的多年工作經驗來說，使用AB雙液型Epoxy(環氧樹脂)灌膠真的是項非常討人厭的製程，因為眉角(台)非常多，產線的紀律更是重中之重點，因為之要操作稍有不慎就會將自己傷得很重，所謂傷得重是指報備損失大。

2024年7月2日 · Epoxy resin is a good insulator that keeps motors, transformers, generators and switches clean, dry and prevents them from short-circuiting. The material is also used in the electronics manufacturing industry where it can be used as an epoxy resin curing agent, semiconductor sealant and to produce printed circuit boards.

2022年7月26日 · Cavist Manufacturing has recently adapted transfer molding technology, using the same process from IC encapsulation to package electronic assemblies at the board (PCBA) level. Any printed circuit board assembly can be inserted into a mold, and completely encapsulated with extremely robust epoxy molding compounds.

PCB encapsulation epoxy is a popular choice for circuit board encapsulation due to its excellent adhesive properties, mechanical strength, and resistance to chemicals and moisture. Epoxies are thermosetting polymers that form a strong, rigid bond when cured.

2025年1月4日 · PCBA coating, also known as conformal coating, is a polymeric film-forming product that protects circuit boards from moisture, dust, chemicals, and temperature extremes. It conforms to the contours of the board and components, providing a protective layer without significantly increasing the size or weight of the assembly.

Epoxy and polyurethane resins are excellent insulators against aggressive environments and contribute to the mechanical protection of the PCBs. Epoxy resins and polyurethane are used for protection in thickness. These systems generally two liquid component when mixed climb quickly in viscosity until fully cured.

2023年12月4日 · Epoxy resins are thermosetting polymers that can be cross-linked with themselves or other co-reactants, such as polyfunctional amines, acids, phenols, alcohols, and thiols. This cross-linking process, also known as curing, results in the formation of a strong and durable material with exceptional mechanical strength, high thermal resistance ...

2023年8月7日 · BT-Epoxy is a type of epoxy resin commonly used in the PCB (Printed Circuit Board) industry for fabricating printed circuit boards. It is a mixture of epoxy resin and BT resins, which are composed of bismaleimide and cyanate ester. BT-Epoxy is known for its exceptional electrical and mechanical properties, as well as its excellent thermal ...

Epoxy coatings shield delicate PCB components and traces from environmental stresses that could otherwise impede functionality or shorten product lifetimes. This article explores roles of epoxy in PCB manufacturing and applications including: We’ll examine how appropriate epoxy selection allows optimizing PCB protection.

Compared to CNC machined metal enclosures, overmolding reduces piece count, assembly labor, and overall system cost. The molded plastic or epoxy housing integrates sealing, mounting features, and aesthetic details into a single part.
