Abstract

The invention discloses a circuit board device, and the circuit board device comprises: a substrate (100) which is provided with a first bonding pad (110); a chip module (200) wich is provided with asecond bonding pad (210), wherein the first bonding pad (110) is electrically connected with the second bonding pad (210), and a filling space (300) is formed between the chip module (200) and the substrate (100); a supporting piece (400) which is supported between the substrate (100) and the chip module (200); and a filling part (500) which is filled into the filling space (300) . According to the scheme, the problem that the packaged chip is prone to short circuit in the packaging process on the circuit board can be solved. The invention further discloses a preparation method of the circuitboard device and electronic equipment.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a circuit board device, a preparation method thereof, and electronic equipment. Background technique [0002] At present, chips generally have WLCSP (Wafer Level Chip Scale Packaging) packaged chips according to the package type, BGA (Ball Grid Array Package, ball grid array package) packaged chips, LGA (Land Grid Array, grid array package) Package) packaged chips and QFN (Quad Flat No-lead-Package, square flat no-lead package) packaged chips, etc., in which the upper layer of the packaging structure of the LGA packaged chip is a plastic packaging material, and the lower layer is a packaged carrier board, but the LGA packaged chip There is only a pad at the bottom, and solder paste needs to be printed on the circuit board for soldering when soldering at the board level. [0003] In the specific board-level soldering process, when the LGA package chip is mounted on the cir...
