Application of magnetic pulse welding technique for flexible printed circuit boards (FPCB) lap joints

Mechanical property and microstructure of aluminum alloy-steel tubes joint by magnetic pulse welding

“…However, in consideration of the production and processing cost compared to steel, aluminum alloy is more economical when it can be used in hybrid structures with steel. In order to obtain these hybrid structures, the proper joining methods (especially welding processes) for aluminum-to-steel dissimilar combinations are necessary [1][2][3][4][5][6][7][8][9][10][11].…”

“…Specific processes investigated include resistance spot [5,6,8], friction stir [7,9,10], diffusion [12], magnetic pulse [2,3,[13][14][15][16], and explosion welding processes [17], and electric discharge [18], laser beam [19,20], laser and GTAW [21], and laser roll [22] welding processes.…”

“…The use of solid state joining process generally is associated with reduced formation of these intermetallic phases [7,9,10,14,15]. And magnetic pulse welding is one of this special welding processes [1][2][3]13].…”

“…The MPW process can be used to join mechanically and weld similar or dissimilar metal tubes and sheets [2,4,6,23,24].…”

Effect of Hygrothermal Treatment on Reliability of Thermo-Compression Bonded FPCB/RPCB Contact Joints

“…[1][2][3][4] FPCBs can be applied to various electronic products, such as portable electronics and display modules etc., due to their many advantageous properties including lightness, small thickness, high glass transition temperature, and superior exibility. [5][6][7][8][9] On the other hand, RPCBs have a low cost, high packaging density, and considerably better established reliability data. Recently, electronics manufacturers have shown increasing interest in the development of electrical and mechanical bonding techniques of electrodes, between FPCBs and RPCBs.…”
