Electronic Insert Molding - Introduction
Electronic Insert molding is a fast growing segment of the cable assembly industry. As products become more mobile and compact, insert molding of
PCBs within the cable assembly becomes a desirable and cost-effective alternative to on-board electronics. These devices are typically referred to as smart cables or dongles
The demand for robust and portable interconnect devices spearheaded new design approaches. Many of these devices evolved into over-molded
products. Today the cable assembly industry, in general, has matured significantly. However, few manufacturers have gained our depth of
experience in insert molding even small, very high-density connectors and utilizing high precision control systems in the injection molding process. So, while insert molding is not a candidate
for all applications, the right mix of insert molding experience, and product design makes for an unbeatable combination.
Electronic Insert Molding Advantages
Over molding of a PCBA device is a practical approach when the size of the PCBA is no
larger than 4 X 4 X 1" and it has a cable attached.Some of the key benefits are:
There are two types of bonding that occur in insert molding, molecular and mechanical. Molecular bonding can
occur when the insert material is the same as or similar to the encapsulating resin. This yields the best results both
in terms of physical strength and leak resistance. . Mechanical bonding can occur in two ways, by the shrinking of
the encapsulating resin around the insert as the resin cools, or by the surrounding of irregularities in the surface of the insert by the encapsulating resin.
Electronic Insert Molding Design Considerations
In general, the basic design rules for insert molding are the same as those that apply to injection
-molding. However, designers should also be aware of the following elements that may affect the design of their parts:
These elements determine what encapsulating resins will work for the application. They also establish the type of
material preparation that must be performed on the insert in order to ensure proper performance of the finished part.
