A spacer comprises two interlocked beams, each folded from a sheet of corrugated paperboard so as to have a base panel and panels on each side of a plane intersecting the base panel approximately at a right angle. In each beam, the panels on each side include a side panel extending from the base panel, an outer panel extending inwardly from the side panel approximately to the intersecting plane, an inner panel extending from the inwardly extending outer panel approximately to the base panel, and panels bracing and reinforcing such beam. Each beam has a notch opening at the base panel and receiving a portion of the other beam. Two tongues including portions of the base panel and portions of the side panels project toward each other and project partly over the notch. Each beam has recesses extending along folds and receiving the projecting tongues of the other beam.
摘要:
A rigid-flex printed circuit board having a rigid section and a flexible section extending from the rigid section is disclosed. The rigid-flex printed circuit board is capable of withstanding high temperatures experienced in high volume production environments utilizing infrared reflow ovens by providing spacers and covers for protecting the flexible section from high temperatures. A process for assembling components and devices on the rigid-flex printed circuit board in a high volume production environment utilizing infrared reflow ovens is also disclosed.
