Abstract

The invention relates to a reinforcing plate, a flexible printed circuit board and a dispensing method. The reinforcing plate comprises a reinforcing substrate, and at least one gap penetrating through a thickness direction of the reinforcing substrate is etched on the reinforcing substrate. A strippable coating is included and is coated in at least one gap on a lower surface of the reinforcing substrate, strippable paint is fully filled in the strippable coating, and the strippable paint filled in at least one gap is flush with an upper surface of the reinforcing substrate. Therefore, when adevice on the upper surface of the reinforcing plate is dispensed, the gap on the reinforcing plate is filled with the strippable coating so that a liquid glue cannot flow to the gap and directly flowto a position between the device and the reinforcing plate, and after the liquid glue is solidified, the strippable coating on the reinforcing plate can be directly peeled off so that the gaps for reducing an internal stress can be ensured to exist on the reinforcing plate, the gaps do not influence glue dispensing between the device and the reinforcing plate, and a good glue dispensing effect isensured while flatness is improved.

Description

technical field [0001] The invention relates to the technical field of flexible printed circuit boards, in particular to a reinforcement board, a flexible printed circuit board and a dispensing method. Background technique [0002] Flexible Printed Circuit Board (Flexible Printed Circuit, referred to as FPC), also known as flexible circuit board, is a kind of highly Reliable, printed circuits with excellent flexibility. Flexible printed circuit boards have the advantages of small size, light weight, high flexibility and excellent electrical properties, and meet the needs of high density, miniaturization, light weight, thin shape, and high reliability. [0003] Due to the flexibility of the flexible printed circuit board, when the flexible printed circuit board is used to make related electrical devices, the strength of the flexible printed circuit board must be increased by using a reinforcing plate. Strong plate surface to achieve a certain mechanical stability. In the c...
