Micro-chip transfer printing device and system

Abstract

The invention relates to the technical field of transfer printing, and discloses a micro-chip transfer printing device and system. The device comprises a press head substrate; a transfer printing array layer which is disposed at one side, facing a bearing substrate, of the press head substrate, is used for the transfer printing of a miniature device on the bearing substrate, and comprises a plurality of transfer printing blocks distributed on the press head substrate in an array, wherein each transfer printing block has a non-pick-up state and a pick-up state for picking up the miniature device, and the switching of each transfer printing block between the non-pick-up state and the pick-up state is independently controllable. The switching of each transfer printing block the device betweenthe non-pick-up state and the pick-up state is independently controllable. The device can achieve the patterning of the transfer printing array layer, achieves the simultaneous transfer printing of alarge number of miniature devices, also can change the patterns of the transfer printing array layer according to different transfer printing requirements, achieves the application of the transfer printing array layer under different transfer printing demands, avoids the complex replacement operation of a transfer printing head, and reduces the transfer printing cost of the miniature devices.

Description

technical field [0001] The invention relates to the technical field of transfer printing, in particular to a microchip transfer printing device and a microchip transfer system. Background technique [0002] A microchip is an integrated circuit chip made of microelectronics technology. It has developed into the Gigabit (core GSI) era. Portable supercomputers, electronic notebooks, miniature translators and portable phones made of microchips have gradually become popular. Appear. [0003] With the birth of the micro-pitch LED display, the micro-pitch LED display has been more and more used in Command center hall, control room, conference center and other key places. With the continuous shrinking of the pixel pitch of the micro-pitch LED display, people's viewing distance is further shortened. [0004] However, regardless of microchips, microsensors, microLEDs and other devices, the transfer and packaging of small-sized chips are still difficult, especially the technology fo...

Problems solved by technology

Specifically, the principle of single-chip transfer printing equipment is: use the indenter to directly press the microchip from the stretch film to the circuit board. However, this method cannot correspond to ultra-thin and small sizes, and the transfer rate is low and the production efficiency is low. Low; the principle of batch transfer printing technology is: transfer in batches through intermolecular force or magnetic force, but the graphics transferred by this transfer printing method can only be transferred according to the surface graphics of the transfer head, and the patterned transfer cannot be flexibly realized. print
