Abstract
An adjustable heater bar arrangement (8) for integrated circuit attachment and removal apparatus including a base plate having four slots (14) in which heater bars (12) are slidably mounted and held in position by clamping screws (18). By directing the slots (14) at an appropriate angle, inward and outward movement of the heater bars (12) is accompanied by lateral movement of each heater bar (12), such that the device (8) may be adjusted to accommodate large and small sized ICs (13A, 13B), as well as lot-to-lot variations between ICs (13A, 13B). For example, to accommodate a square IC (13A, 13B), each slot (14) extends outward at an acute angle of 45 degrees, respectively, with reference to the sides of a substantially rectangular base plate (10).
