Abstract:
Board delamination during the singulation from a board panel and board sagging during front-end assembly are two of the biggest problems encountered in cellular manufacturing lines. The method and circuit board panel (600) of the present invention substantially eliminate assembly-line delamination and sagging for circuit board manufacturing. A number of slots are punched to fit into a circuit board profile. V-grooves (606, 608) are cut along each of the circuit board profiles through the slots and directly opposite on a top and bottom of the circuit board. Thus, optimization of the cut-outs (604) and v-groove (606, 608) configurations tearing, delamination are eliminated, and sagging is substantially reduced.
Abstract:
A selective gas sensor (10) for detecting a particular compound, or group of compounds, such as non-methane hydrocarbons, within a high temperature gas stream (12) includes an oxygen generation sytem (14) positioned over an oxygen diffusion region (15). The oxygen generation system (14) and the oxygen diffusion region (15) provide oxygen through a medial temperature control zone (20) to a sensing element (16). The temperature and flux of hydrocarbon components within the high temperature gas stream (12) are regulated by components within the high temperature control zone (20) and by an external temperature control zone (22) in thermal contact with the sensing element (16).
