Advantages of Overmolded Electronic Inserts
In general, Overmolding of a PCBA device is a practical approach when the size of the PCBA is no larger than
10cm X 10cmX 2.5cm and it has a cable attached.
At this point, the real advantages of an overmolded design come into play:
The Injection Moulding PVC Compound used has a moulding temperature between 160 to 180 Deg C and the
typical moulding pressure is approximately 30pa.
Direct Electronic Insert Overmolding
Conventional wisdom would seem to indicate that inserting an electronic device into a 30 ton molding press and
injecting hot thermoplastic materials at 350°F and 400 psi would not be a wise choice.
However, depending on the PCBA layout and component structure, developing a design with an internal clamshell
can eliminate many of the obstacles associated with direct overmolding. This configuration can protect the PCBA
and provide a consistent substrate for molding (see Figures 5 and 6).The cost of the discreet clamshell is relatively low, as it is an internal part and can often be soft-tooled.
While not a candidate for all applications, and not a good choice with all suppliers, the right combination can make
direct PCB overmolding an unbeatable solution.
