In recent yearsminiLEDDue to its explosive growth and excellent performance, it can greatly enhance the user experience of the monitor and is deeply loved by consumers. All major display manufacturers are developing it one after anotherminiLEDWe will vigorously produce and launch the products. Solder paste, as a new type of soldering material, will naturally not be absent eitherminiLEDToday, the solder paste manufacturer will talk about the manufacturing of displaysminiLEDWhat conditions are required for solder paste in the chip crystal bonding process?

How to understand the crystal piercing process?

The crystal piercing process is inminiLEDOne of the processes used in the manufacturing process refers to the use ofminiLEDA chip is a technology that pierces a wafer and transfers the chip onto another substrate.miniLEDThe emergence of technology enables the manufacturing of high-density chips while ensuring the quality and stability of the chips. Compared with the traditionalCOBIn terms of technology,miniLEDThe chip size is smaller, the pixel density is higher, and it can achieve higher resolution and better color performance.

Solder paste.PCBIt plays a role in connecting metal components and during the manufacturing processPCBThe function of the board is that it can fix the components inPCBOn the board, the connection of the circuit is realized.

inminiLEDIn the process of magnetic crystal transfer of chips, the main role of solder paste is tominiLEDThe chip is fixed on the substrate for subsequent processing and packaging.

Overall, solder paste, as a kind of adhesive with good electrical conductivity, is generally composed of conductive particles, resins and solvents, etc. inminiLEDThe entire process of magnetic crystal transfer of the chip cannot only ensure the conductivity of the solder pasteminiLEDThe electrical signal transmission between the chip and the substrate is ensuredminiLEDThe normal operation of the display and backlight, as well as the viscosity and consistency of the solder paste, can also be helpfulminiLEDThe chip is fixed on the substrate to prevent it from shifting or falling off during the subsequent production process.

To sum up, solder paste has played an enhancing role in this processminiLEDThe role of chip reliability and stability is guaranteedminiLEDHigh quality and long lifespan of the display and backlight.

miniLEDWhat conditions are required for solder paste in the chip crystal bonding process?

From the above discussion, it can be judged that inminiLEDThe entire process of the magnetic crystal transfer technology for chips has certain requirements for the adhesion and conductivity of the solder paste.

In terms of adhesion:Solder pasteIt must have sufficient adhesive force to be able tominiLEDThe chip is firmly adhered to the substrate to ensure that there will be no deviation or loosening and falling off during the process. Of course, the adhesion of the solder paste should not be too strong; otherwise, it will be very difficult to remove in the subsequent production processminiLEDChips need to be flexibly replaced according to the nature and surface condition of the substrate material. The relatively smooth surface requires solder paste with strong adhesion to ensure the stability of the chip. If the substrate is rough, a solder paste with slightly lower adhesion is needed to facilitate easy removal in subsequent processing.
