PCB minor editing: precision and effICiency of SMT chip processing

The precision of SMT mounting processing includes the positioning precision, the repetition precision and the resolution of the SMT mounting machine. Through load balancing, in order to improve the placement efficiency, some measures are taken to pick up as many heads as possible. The SMT chip processing manufacturer will introduce relevant contents in detail below.

1. Positioning accuracy of the placement machine.

The positioning accuracy refers to the deviation between the actual component position and the component position. The factors affecting the component accuracy include translation error and rotation error. The translation error mainly coMES from the X-Y axis positioning system. The rotation error refers to the insufficient accuracy of the component centering mechanism.

2. The repeatability of the mounter.

Repetitive precision means that the placement machine is repeatedly instalLED at a specific coordinate position, and the resulting deviation is the repetitive precision. Therefore, the sample accuracy given by the SMT mounter is shown as the repeated accuracy of the mounter.

3. The resolution of the mounter.

After receiving the pulse command signal, the resolution of the R axis of the mounting head is the resolution of the mounting machine. The rotation degree of the R axis of the mounting head is 0.0024/pulse reaches 0.0024/pulse. The minimum increment of the resolution machine operation. The motion accuracy of the machine itself is an important energy indicator.

Improve the efficiency of SMT chip processing

1. SMT mounting machine itself. SMT chip mounter itself has a maximum speed value, but it is usually difficult to achieve this. It has a certain relationship with X/Y structure mounter. In terms of placement speed, head configuration measures should be taken as far as possible. In addition, in the placement process, components of the same type are placed together to reduce the number of assemblies and save placement time.

The whole production process of SMT chip processing line actually involves a lot of equipment, but if any equipment runs too slowly in the processing process, it will delay the whole chip process and affect the realization of the actual process. Therefore, we should not only have scientific and systematic theoretical guidance, but also have experienced personnel to operate on site to maximize our expectations.

PCB manufacturers, PCB designers and PCBA manufacturers will explain the precision and efficiency of SMT chip processing.
