  Since the birth of the membrane switch, it has experienced several technological innovations. JRPanel would like to talk about the development trend of membrane switch technology today . Multifunctional integrated membrane switch  The traditional membrane switch only has the function of switching on and off, and has a single function. According to the needs of instruments and meters, electronic components (including RC components, inductance components, light-emitting devices, sound-emitting devices, etc.) have been installed into membrane switches, and new light storage and fluorescent inks have been applied. The membrane switch integrates multiple functions such as switches, decorations, regular panel notes, luminous displays, and sound prompts, and realizes part of the circuit board functions.   Screen printing isolation layer   The structure of the membrane switch requires that the two circuits must have an isolation layer, which plays ...

Circuit design software is widely used, and modern circuit design cannot do without circuit design software. Among many circuit design software, protel is a commonly used one. In order to enhance everyone's understanding of circuit design software and protel, this article will introduce how to convert Protel 99se design into PCB projects in DXP based on this circuit design software . In addition, this article is only the first one, please refer to the next one for more content. 1. Generate the project Simply open the database file in the DXP menu, and you can convert a 99SE database file into a project in DXP. Make sure this operation starts a two-step process. First, the contents of all database files are placed in a new Windows folder (has the same name as the database file and stored in the same path). Secondly, some nearby files are generated and opened in DXP, which is a project group file with several independent project files. When your 99SE database contains multiple types ...

  1. Shape: shape, conductor line, insulation treatment, liner combination, etc. should meet the requirements of the drawing or provide physical samples. 2. Material: panel, substrate, silver paste, carbon ink, spacer, adhesive, adhesive, reinforcing plate, insulation printing should meet the requirements of the drawing. 3. Check appearance quality: The scope of this inspection is wide.    Panel: There must be no obvious defects (such as lack of strokes in characters that affect readability; stains, light transmission points; deinking, stains, scratches; transparent window overflow, residual glue, etc.); no offset phenomenon (printing sleeve Plate deviation ≤ 0.2mm; upper and lower line key combination deviation ≤ 0.5mm; circuit and key sheet, panel and face key combination deviation ≤ 0.3mm; panel and circuit combination after the surrounding blank area deviation ≤ 0.2mm; panel The offset between the button bump and the substrate is less than or equal to 0.5mm).   ...

  Engineers who are just getting started or just entering the electronic design position, may don't know how to construct a good PCB, or even what the layers are, how to define and distinguish when they get a board. Next, we will take you to uncover the veil of PCB and explain each layer in detail. Layer Description Top Layer Mainly used to place components , and can be used for wiring for laminates and multilayer boards Mid Layer There can be up to 30 layers, which are used to route signal lines in multilayer boards Bootom Layer Mainly used for wiring and welding, sometimes components can also be placed Top Over layer Used to mark the projection outline of the component, the label, nominal value or model of the component, and various annotation characters Bottom Over layer It has the same function as the top silk screen layer, if all kinds of labels are contained in the top silk screen layer, then the bottom silk screen layer is not needed I...
