ABSTRACT:
An LGA contact (40, 40′) for electrically connecting an IC package (32, 32′) and a PCB (34, 34′) includes a vertical basic part (42and44, 42′and44′), a vertical section (43, 43′) bendedly outwardly extending from a lateral side of the vertical basic part, an arm (48, 48′) extending upwardly from a top of said vertical section and a contacting portion (49, 49′) extending from an distal end of the arm. The arm has a rearwardly extending portion (482, 482′) and a forwardly extending portion (480, 480′). Further, two projections of the vertical section and the vertical basic part on a horizontal surface form an acute angle therebetween, thereby the arm can be devised to be relatively long to get good spring characteristics and many of this kind of contacts can be arranged in a relative less pitch as being assembled a housing (50, 50′).
