Embodiment Construction

[0046] One embodiment of the present invention comprises utilizing computer to generate PCB encapsulation data table, and the PCB encapsulation data table includes the bit number information in PCB, checks whether the bit number in the PCB encapsulation data table is unique; if not unique, output repeating bit number .

[0047] Use a computer to generate a BOM data sheet, which contains the bit number information in the EBOM, and check whether the bit numbers in the PCB package data sheet correspond to the bit numbers in the BOM data sheet; if not, output No corresponding bit number.

[0048] The BOM data table also includes the material coding information in the EBOM and whether the device is a through-hole device or a surface-mount device information, and the PCB package data table also includes the layer information of the device in the PCB and the package name information in the PCB ;

[0049] Include the following steps:

[0050] A. Specify the wave soldering surface a...

Abstract

The invention discloses a PCBA (Printed Circuit Board Assembly) manufacturability inspection method which utilizes a computer to generate a PCB package datasheet containing position number information in a PCB; checking if the position numbers are sole or not; outputting repetitive position numbers when the position numbers are not sole; utilizing a computer to generate a BOM datasheet containing position number information in an EBOM; checking if the position numbers in the PCB package datasheet are consistent with the position numbers in the BOM datasheet one to one; outputting inconsistent position numbers when inconsistency is found. According to the invention, full check can be conducted to the manufacturability of a PCBA. The method is capable of finding out errors such as repetition of position numbers in a PCB, inconsistency between position numbers in a PCB and an EBOM, non-use of standard package, mistaken use of standard package and the material height beyond technical requirements. With the method, the blind areas and difficult points in manual browsing inspection are overcome, high inspection efficiency can be achieved and the producing cost of a PCBA is reduced.

Description

technical field [0001] The invention belongs to the technical field of electronic production and manufacturing, in particular to a PCBA (Printed Circuit Board Assembly, printed circuit board assembly) manufacturability review method. Background technique [0002] During the PCBA manufacturability review process, we hope to find problems as much as possible, so as to avoid the problems being exposed during the trial production, resulting in unnecessary losses. [0003] At present, in the PCBA manufacturability review process, only manual browsing review is performed on the PCB, so only the problems that can be found by visual inspection can be reviewed (such as whether the required marking is complete, whether the silk screen overlaps, whether the barcode frame is placed and whether it is placed properly, etc.). [0004] Since the number of bit numbers on the PCB ranges from dozens to hundreds, the manual browsing review cannot review the following issues: PCB bit numbers are...
