Abstract

The invention provides a device for accurately bending a printed circuit board. The device comprises a base, a micrometer, a fixed arm and a pressing block, wherein two gaskets on the base are used for bearing the printed circuit board; the micrometer comprises a rotating part, a fixed part, and a shaft part which is linked with the rotating part; the fixed arm is fixed on the base and is used for fixing the fixed part of the micrometer; and the pressing block is fixed on the shaft part of the micrometer in a rotatable way.

Description

Technical field [0001] The invention relates to a device for accurately bending a printed circuit board. Background technique [0002] In recent years, due to the more and more progress of ceramic film overlay technology, the number of ceramic film overlay layers has increased, which has made the capacitance of multilayer ceramic capacitors higher and higher, and can gradually replace the low and medium capacitance aluminum electrolysis Capacitors and tantalum capacitors. Chip ceramic capacitors can be directly pasted through SMT, and the production speed is faster than aluminum electrolytic capacitors and tantalum capacitors. In addition, they have the characteristics of small size, stable temperature characteristics, and wide application range. [0003] Assessing the firmness of the bonding between the terminal electrode of the chip ceramic capacitor and the ceramic substrate is to subject the capacitor body and the substrate to be welded to a bending stress, and to monitor the ...
