Background

With the progress of packaging technology, chip integration is continuously improved, the number of I/O pins is rapidly increased, power consumption is increased, and the requirements for integrated circuit packaging are more strict, so that ball grid array packages (i.e. BGA packages) are beginning to be applied to production in the 90 th 20 th century, and the technology becomes the best choice for high-density, high-performance and multi-pin packages such as CPUs, south-board chips and north-bridge chips of motherboards. However, because of the characteristics of the ball-shaped pins, the area of the substrate occupied by the BGA package is large, and in order to make the volume of the packaged substrate smaller and the integration level higher, the packaging industry is turning to the application and development of the needle-shaped pin array package. The biggest difference of the needle implantation relative to the ball implantation is that the ball has no directionality, and the needle has a certain direction, so the needle implantation is more difficult and more demanding relative to the ball implantation.

The existing needle implanting technology mainly uses mechanical pins, namely a high-speed motion mechanism is used, a gripper is arranged at the tail end, the pins are sequentially implanted on a substrate, 10 pins can be implanted into the substrate at the fastest speed per second, the efficiency is low, the consumed time is long, and the pins which are smaller than a certain diameter or length cannot be correspondingly implanted.
