I. Installation accuracy scale of SMT patch machine
SMT patch machine mount accuracy refers to the center of our are ready to mount components and the Z large offset of the corresponding PCB board, generally we need this value does not exceed 3%.Mount accuracy is to detect SMT patch machine can normal fast and accurate operation of the basic requirements, if a low accuracy SMT patch machine it can only mount SMD or various types of circuit assembly components, and mount higher accuracy of SMT patch machine can mount more lead, fine spacing of all kinds of components, more suitable for producing electronic equipment and military equipment.
II. The resolution scale of the smt patch machine
SMT patch er resolution refers to the ability to connect points in space during its work.SMT patch machine resolution we can become the Z small increment-a measure of machine movement, so when we measure the accuracy of SMT patch machine, it is a relatively important hard target.However, generally we rarely use resolution as a parameter when describing the performance of SM patch machine, generally it does not appear in the technical standard of SMT patch installation, as long as when we compare the process of two patch machine, to use the resolution for comparison.3. Repeat accuracy scale of SMT patch machine
The SMT patch machine repetition accuracy refers to the offset value in which we mount the same element at the same position.In fact, it is also a good Z-method method to measure the accuracy by adopting systematic statistics during processing and production.Repeat accuracy depicts the ability of the mounting tool to repeatedly return the calibration point.The smaller the value is, the more accurate the fit is.
