Printed circuit boards in the role of electronic equipment: transistors, integrated circuits, resistors, capacitors, inductors and other components to provide a fixed and assembled mechanical support, the realization of transistors, integrated circuits, resistors, capacitors, inductors and other components of the wiring and electrical connections between the electrical insulation to meet the electrical characteristics of the electronic assembly process for the inspection of the components, maintenance, provides the identification of characters and graphics, for wave soldering provides a solder resist graphics. graphics, and provides solder resist graphics for wave soldering.
When the electronic equipment using printed circuit boards, due to the consistency of similar printed circuit boards, thus avoiding the error of manual wiring, and can realize the electronic components automatic insertion or placement, automatic soldering, automatic inspection, to ensure the quality of the electronic equipment, improve labor productivity, reduce costs, and easy maintenance.
Expanded Information:
Note:
Single panel pads must be large, and the wires connected to the pads must be thick enough to put in teardrops if you can.
Single-panel only one side of the line, if the DIP part is placed on the front, the line goes to the back; if the part is placed on the back, the line goes to the front. If there are SMD components, SMD components and DIP components must be different sides, and the line must go in the SMD side.
Enabling teardrops: Generate teardrops on the Routing page of Options must be checked in order to generate teardrops.
When you can't get the wires out of a single panel, you can play jumpers, but the principle of jumper wires is the less the better, and the shorter the length of the jumper wires, the better. The jumper is divided into DIP jumper and SMD jumper, customary single-panel front set DIP parts, back set SMD parts and alignment. DIP jumper on the front, SMD jumper is put on the back.
