drills holes in the panel. It may also mean an indivisible graphic object,.e. PCB designer One who creates the artwork for printed circuit boards. Examples: in register, off register. It includes a "Laminate Selector Chart" entitled "PCB Material Properties and Recommended Application Areas" HDI PCBs: Choosing The Right Material A comparison of many brands of PCB laminates can be found at the Standard Printed Circuits "Microwave Laminates Comparison Chart". Other free Gerber viewers require one to set up the Gerber files each time and won't allow saving the set-ups unless one buys an upgrade. Depending on which system it is designed for, one type of DUT board is used in testing individual integrated circuits in a silicon wafer before they are cut free and packaged, and another type is used for testing packaged IC 's.

Rise times are charactericstic of the technology being used in a circuit. This is a "word chain." A bad dictionary needlessly sends the user on endless word chains. "If the ground returns are common, they can be connected at a single point near the external ground connection, which is good EMC practice." - Jon Berrie, Technical Marketing Specialist Hot-Stage, Zuken. Sometimes vias are tented on the top side of the board and left uncovered on the bottom side to permit probing from that side only with a test fixture. Beam lead A metal beam (flat metallic lead which extends from the edge of a chip much as wooden beams extend from a roof overhang) deposited directly onto the surface of the die as part of the wafer processing cycle in the fabrication. (From the viewpoint of a printed circuit designer serving engineers or customers, this inability to save set-ups makes the competing free Gerber viewers completely useless for sharing Gerber data.) gerber or Gerber see Gerber file. Some manufacturers take advantage of the large bed size of the largest Gerber photoplotters, roughly the size of a full-sized billiards table. Although these terms are descriptive, there are no industry- wide standards for sizes. Fine pitch Refers to chip packages with lead pitches below.050". The tabs are strong enough so that the sub-panel can be assembled as a unit, and weak enough so that final separation of assembled modules is easily done. Each wire is inserted in a hole in the terminal block, and then anchored by means of a screw. Netlist List of names of symbols or parts and their connection points which are logically connected in each net of a circuit.
