Application of laser soldering in connector industry
Connector industry as an important branch of the electronics industry and the core industry, is one of the most widely use electronic components, widely used in computers, telecommunications, communications, household appliances, industrial electronics, aerospace and automotive electronics and other fields, with industry downstream of large scale, product status important, wide application, etc. The overall development of the connector industry is characterized by: high speed, digitalization and integration of signal transmission ;Product size is small, narrow spacing, multi-function; The convenience of plug and unplug and module combination; The low cost of products.
Along with the electronic products of high technology, miniaturization, high performance-based trend has become increasingly apparent, people has higher requirement for connector, part of the connector soldering demand is higher and higher, the traditional welding processing mode can't meet the demand, as a kind of non-contact laser soldering process means more and more get the favour of manufacturers.
The main applications of laser soldering machine in the connector industry are: marking, welding (weld welding and soldering).This is mainly about welding: weld welding is the most classic laser application, in the connector industry is mainly used for metal structural parts fixing, structural strengthening, ground wire connection, etc. .For example, in the processing of Type-C, laser fusion welding is applied to the welding of Type-C fixing piece and shell. It adopts spot welding, 4-8 points, to strengthen the tensile strength of the interface. Laser welding-welding system (150W YAG laser) can be applied.
Connector soldering methods are currently mainly reflow soldering, wave soldering, soldering iron three ways.
Laser soldering belongs to the supplement of various welding methods, the main competitor is manual welding. The traditional method can not be welded by laser soldering to supplement the solution. For example, in the welding of Display Port wire, due to the particularity of wire, manual soldering iron welding and hot pressing welding can not solve the welding problem perfectly. The advantages of laser are highlighted, its non-contact and single point welding can solve most of its problems, but there are some problems that laser can not solve such as splashing.
As the international transfer of connector manufacturing center of gravity to the mainland, China a connector industry will keep growing trend, connector to low-end fields in China before, but in recent years, along with the rise of domestic manufacturers and technology gap narrowed, the entire industry is toward high-end field forward, and application of laser soldering in connector will increasingly nots allow to ignore.
