How does PCB design lay out components
Layout is divided into two ways, one is interactive layout, the other is automatic layout, is generally adjusted on the basis of automatic layout with interactive layout, in the layout can be redistributed according to the situation of the line, the two g
How to deal with the quality problem of patch processing plant
The size of SMT steel mesh thickness is mainly determined by the spacing of PCB circuit board welding components, if the spacing is small, the selection of thinner SMT steel mesh. If the spacing is large, choose the thickness of SMT steel mesh.
How to distinguish PCB circuit board welding
Because some standard thickness of the circuit board is not the same size, so the customer can measure some checks, according to their own product thickness and specifications, and then the light and color, in the external circuit board and ink cover, fol
