Abstract

The invention discloses a manufacturing method of an ultrathin package substrate and a related product. The manufacturing method can help solve a technical problem that the ultrathin package substrate is low in machinability, each to be injured or damaged in the machining process due to insufficient strength. The method comprises the following steps: providing an ultrathin copper-clad plate; forming a rigid reinforcing layer on a non-working region of the ultrathin copper-clad plate; performing conventional line machining on the working region of the ultrathin copper-clad plate; and performing shape machining on the ultrathin copper-clad plate to remove the non-working region, thereby manufacturing the ultrathin package substrate.

Description

technical field [0001] The invention relates to the technical field of packaging substrate processing, in particular to a method for manufacturing an ultra-thin packaging substrate and related products. Background technique [0002] At present, IC packaging is developing towards thinner and smaller, and the packaging substrate is also developing towards thinner. For example, in the field of integrated circuit packaging such as micro-electromechanical system sensor product modules, it needs to be applied to ultra-thin packaging substrates or thin packaging substrates. When the thickness of the finished plate reaches 100 μm or less, the strength of the product manufactured by the traditional process is insufficient, resulting in difficult processing and low yield. [0003] In the traditional manufacturing process, the ultra-thin packaging substrate is mainly processed through the coreless substrate process. The processing process generally includes: [0004] S1, making the ca...
