Method for inspecting the insertion state of a plurality of pins inserted into a substrate, and substrate inspection device

Abstract

The substrate inspection device for inspecting the insertion state of a plurality of pins inserted into a substrate may include: a communication circuit that communicates with a pin insertion device; The inserted first substrate irradiates patterned light; an image sensor that receives patterned light respectively reflected from a plurality of first pins; one or more memories that store pin insertion reference information; and one or more processes device. One or more processors may generate pin insertion status information on each of the plurality of first pins using the patterned light reflected from the plurality of first pins, respectively, using the pin insertion reference information and the plurality of first pins. At least one of the respective pin insertion status information of the pins, detecting at least one second pin with poor insertion among the plurality of first pins, based on the pin insertion status information about the at least one second pin, generating a control signal for adjusting at least one first process parameter of a plurality of process parameters of the pin insertion device, and controlling the communication circuit to send the control signal to the pin insertion device.

Description

technical field [0001] The present disclosure relates to a method and a substrate inspection apparatus for inspecting the insertion state of a plurality of pins inserted into a substrate. Background technique [0002] In general, a pin insertion device inserts a plurality of pins into a plurality of holes formed on a substrate, for example, a printed circuit board (Printed Circuit Board: PCB). The substrate into which the plurality of pins are inserted may be electrically connected to other components or the substrate through at least one of the inserted plurality of pins. Specifically, after the pin insertion device moves the pin insertion head loaded with a plurality of pins to the set pin insertion position, and applies a pin insertion force (force) to the pin insertion fingers, the pin insertion fingers insert The pins loaded by the pin insertion head are press-inserted into holes formed in the substrate. [0003] However, errors may occur in the pin insertion process ...

AI Technical Summary

Problems solved by technology

Therefore, the pins inserted into the substrate may be poorly inserted.

[0004] It takes a lot of time and cost for the user to directly check the insertion status of the pins in order to detect such poor insertion of the pins, and the inspection cannot be performed accurately

In addition, in order to directly improve the poor pin insertion, even if the user takes measures for the pin insertion device, it takes a lot of cost and time, and there is a problem of low productivity.
