摘要： A process for manufacturing surface mountable electrical devices includes the steps of preparing a PTC resistive plate, covering the plate with first and second conductive layers to form a laminate, forming a plurality of spaced apart bores of cross-shaped cross-section in the laminate along intersecting cutting lines at locations where the cutting lines intersect, electroplating the first and second conductive layers and the cross-shaped bores, and cutting the laminate along the cutting lines to form a plurality of polygonal elements with each of the bores being divided into four parts, each having a substantially L-shaped cross-section.

摘要： A surface mountable electrical devices includes a PTC resistive element having opposite first and second surfaces and lateral faces interconnecting the first and second surfaces, spaced apart first and third electrode layers formed on the first surface, a second electrode layer formed on the second surface, and a conductive layer. Each two adjacent lateral faces defines a corner that has a terraced face. The conductive layer has a first lateral segment formed on the third electrode layer, a second lateral segment formed on the second electrode layer, and a transverse segment formed on the terraced face of one of the corners and having a terraced cross-section.
