A laser engraving apparatus (10) and method for engraving a workpiece (15) which includes a mask (11) having at least one image opening (14) extending therethrough. A suction housing (21) is operably coupled to a source of partial vacuum (19) and includes a mouth portion (22) positioned proximate the mask (11) to hold the workpiece (15) and the mask (11) in abutting contact, A laser cutting assembly (24) generates a laser beam (26) which is directed onto the exposed surface (16) under the mask (11) causing engraving thereof. Vaporization or engraving by-products are drawn away from the vaporization surface (16) through the partial vacuum used to hold the mask (11) and workpiece (15) together, The partial vacuum also may be used to cool the mask (11).

Apparatus and method for laser engraving thin sheet-like materials

A disengageable electrical connector structure in which a flexible contact finger is attached to a stationary base and dielectrically isolated from a stationary ground shield attached to the base to facilitate controlling the impedance of the contact finger when in a contact position connecting an electrical circuit to a lead of an electronic device.
