How to choose patch capacitor and patch resistor correctly
With the miniaturization of electronic products and the increase of labor cost, more and more electronics use SMT process, which is converted from plug-in to SMT, greatly improving the production efficiency. Once the quality or production problems of patch components occur, huge economic losses will be caused. How to choose the right type is the key problem that each major purchasing industry needs to learn.
Selection and reading of patch resistance
Patch resistance, full name plate fixed resistance, is one of the metal glass glaze resistors. It is a resistor made by mixing metal powder and glass glaze powder and printing on substrate by screen printing method. With the characteristics of low cost, high stability, moisture resistance, high temperature, low temperature coefficient, can greatly reduce the space cost of the circuit, make the circuit design more sophisticated, products are widely used in mobile phone, PDA, set-top box, instrument, display, computer and other electronic products.
