Multi-chip packaging protective silicone rubber tooling

Abstract

The invention discloses a multi-chip packaging protective silicone rubber tooling which comprises an upper mold device, a lower mold device and a chip placing device. The upper mold device and the lower mold device are connected through a screw rod, and a first placing groove for placing the chip placing device is arranged at the center. The screw rod is used for closing the upper mold device andthe lower mold device. The chip placing device comprises a table plate. Two longitudinal slide rails are arranged in parallel on the table plate. Two transverse guide rails are slidably arranged on the longitudinal slide rails. Two slide bases are respectively slidably arranged on the two transverse guide rails. Chip clamp grooves for placing chips are arranged on the corresponding side surfaces of the four slide bases. The tooling has a simple structure and is convenient to use and realizes simultaneous accurate positioning and clamping of a plurality of chips, and the cavity formed by the upper mold device and the lower mold device becomes a reserved space for pouring silicone rubber so as to meet the requirement of simultaneous silicone rubber packaging of a plurality of chips.

Description

technical field [0001] The invention relates to the technical field of chip packaging, in particular to tooling for multi-chip packaging protective silicone rubber. Background technique [0002] The chip is a precision electronic product. Impurities and water vapor in the external environment will corrode the precision circuit on the chip, which will cause damage to the chip. The protective silicon rubber around the chip can effectively prevent damage to the chip from the external environment. Chip packaging Technology is a process technology that wraps the chip to avoid contact between the chip and the outside world and prevent damage to the chip from the outside world. Impurities and bad gases in the air, and even water vapor will corrode the precision circuits on the chip, resulting in a decrease in electrical performance. Different packaging technologies differ greatly in terms of manufacturing processes and processes, and packaging also plays a vital role in the perfor...

AI Technical Summary

Problems solved by technology

[0003] At present, the chip packaging protection silicone rubber technology or equipment is only for a single chip packaging, and multiple chips cannot be packaged at the same time, which affects the efficiency of packaging, and the existing packaging can only be fixed in one place and cannot be carried out at any time. If in an emergency Next, the chip needs to be packaged, and the chip needs to be taken to the packaging equipment, which is easy to cause damage to the chip
