Abstract

The invention discloses a BGA surface mounting system which comprises a surface mounting mechanism and a PCB positioning and adjusting mechanism. The PCB positioning and adjusting mechanism is placed under a crossbeam, and comprises a vertical and horizontal adjusting device and a positioning clamp mounted on the vertical and horizontal adjusting device; and in the positioning clamp, a fixation disk and locking blocks move up and down simultaneously to clamp a PCB on the fixation plate; the vertical and horizontal adjusting device moves the positioning clamp vertically and horizontally, so that BGA devices are in up and down correspondence with pad positions on the BCB, and then, reflow soldering is carried out. According to the technical scheme, the BGA surface mounting system is simple and reasonable in structure, convenient to install, simple in use and operation and high in working efficiency, the problem that BGA devices are hard to surface mount accurately on the PCB is effectively solved, the work performance is reliable, and the operation precision is high.

Description

Technical field: [0001] The invention relates to a system for placing components such as BGA and CSP welded on a PCB, that is, an electronic printing board. Background technique: [0002] With the miniaturization (such as mobile phones), portability (such as notebook computers) and multi-functional development trends of electronic products, the functions of integrated circuits are becoming stronger and stronger. At the same time, BGA (BallGrid Array ball grid array structure), IC chips in different packages such as CSP (chip scale package) and QFP (Quad Flat Package) are developing in the direction of increasing the number of pins and reducing the pin pitch, which gives a lot to the sample production process. Or manual placement of BGA and other IC devices in small batch production brings difficulties. However, the fully automatic placement machine suitable for mass production is uneconomical for sample production and small batch production. Invention content: [0003] T...
