Abstract

The invention discloses a high-speed hard-soft combining plate with soft areas of different lengths and a manufacturing method thereof. Soft plates of different layers are designed into structures with bending areas, of which the lengths are gradient. When soft areas are bent, pulling and extruding may not occur to ensure same interlayer gaps and further eliminate severe influence on impedance due to change of a referential plane. Signal integrity of the hard-soft combining plate is improved.

Description

technical field [0001] The invention relates to the field of rigid-flex boards, in particular to a high-speed rigid-flex board with unequal soft regions and a manufacturing method thereof. Background technique [0002] Rigid-flex boards are lighter and more space-saving than ordinary circuit boards. Rigid-flex boards are an ideal solution for applications such as aerospace. The flexibility of this board is reflected in the fact that it can be folded, bent, and squeezed into very small spaces. It is suitable for any equipment and can improve the ability of product miniaturization. Rigid-flex boards can also reduce the manufacturing cost of the device, because of its small size, it can reduce the size of the package, thereby reducing the cost of materials required for production. Additionally, the flex circuit portion of the rigid-flex board reduces the need for interconnect wiring and soldered connectors. Make the whole system circuit more reliable and durable. Rigid-fle...
