摘要: A support is provided for a component on a substrate to minimize unacceptable bending or displacement. In a preferred embodiment, a suitable amount of a thermoplastic material is injected through a hole in a PCB under the component after the component has been affixed to the PCB. This allows the support material to fill any space between the component and the PCB yet allow for variation in lead height and for thermal expansion of the support material.
