Q:What is the type of sheet material for double panels
According to the thickness of the distinction, according to the material with melamine MDF and melamine board, the difference is that one is pressed with powder and rubber, one is pressed with wood and plastic
Q:How to judge the use of double-sided ok ok ah
Plate surface should be smooth, no burr groove marks and planer marks, no glue phenomenon, the board without local yellow, black and other pollution.
Q:How to do PCB double panel
Design good pcb file, directly to the system board business on the line, you do not have professional equipment, then make a double panel is more difficult
Q:Can the double panel be used as a wardrobe?
It is a special way that the plywood is present and has a thickness of 3mm. Decorative panels are currently different from the mixed oil practice of a high-level decoration materials.
Q:Is it the same material for the double panel and the cabinet door?
Not the same material, mainly the substrate is not the same, double decorative panel substrate is a representative of the particleboard, paint board substrate is the density board, paint sub-metal paint and piano paint, the two used in the kitchen inside the most. There is a clear difference is that paint can do modeling, double finishes can only do flat.
Q:PROTEL99 PCB double panel how to draw
According to customary painting, are generally the first cloth power and ground. Of course, since you want the system do not cloth GND network is also OK, there are two ways: the first can be all the GND network are changed to 'No Net'.
Q:Pcb double panel if there is a simulated ground and digital to the two to be split?
they and digital ground will be used inductors or 0 ohm resistance or other means connected to a single location. Some of the analog and digital ground of the PCB is divided into copper,
Q:How much is the eco-sided plate?
To use the two sides of the wire, must be between the two sides have the appropriate circuit connection Caixing. The "bridge" between such circuits is called via.
Q:What is the difference between a single panel and a double panel?
Double board is ultra-thin circuit boards, ultra-thin circuit boards, printed circuit boards, printed circuit boards, Kunshan circuit boards, special circuit boards, special circuit boards, circuit mills, circuit boards, soft circuit boards, Flexible board, flexible circuit boards, flexible circuit boards, aluminum-based circuit boards, PCB board, circuit boards, circuit boards, PCB board, aluminum plate, high-frequency board, PCB
Q:How to draw double-panel single-chip? The How is the connection between the board and the board?
The holes used in the double panels are metallized holes, that is, conductive holes, which can connect two layers of wires. In fact, in the automatic routing do not have to consider these, and as long as the double-sided painting, in the processing of these are not to worry about.
