Whether the quality of PCB ink is excellent, in principle, it is impossible to break away from the combination of the above major components. The excellent ink quality is a comprehensive manifestation of the scientific, advanced and environmentally friendly formula. It is reflected in: Viscosity It is an abbreviation for dynamic viscosity (dynamicviscosity). Generally expressed [...]
Circuit board welding method Welding is one of the important links in the manufacture of electronic products. If there is no corresponding process quality assurance, it is difficult for any well-designed electronic product to meet the design requirements. It is impossible and unnecessary to use automatic equipment to make one or two circuit boards in [...]
DfRwk cannot be found in the list of DfX Design Guidelines. DfX refers to various design guidelines collected under the heading "Excellent Design". You may have heard of more popular guidelines, such as design for manufacturability (DFM), design for assembly (DFA), or design for test (DFT). But what about design rework (DFRWK)? DFRWK is not [...]
