What’s The Minimum Required Length of SMT Materials Tape In PCBA Prototype?

What’s the minimum required length of SMT materials tape In PCBA Prototype? Generally, the material for SMT Assembly Prototype and trial production is relatively short, and it is not easy to load the materials. It is necessary to set a standard. So how long is the material tape length, and can the SMT factory accept it?



Minimum Required Length Requirement of Materials Tape For PCBA Prototype 
In the SMT production process, the materials are mainly packaged in trays and tapes. This packaging method is convenient for the placement machine to pick up the material and improve the production efficiency. Among them, the tape is installed on the feeder, and then the pick and place machine takes the material. In the process of PCBA prototype, due to the relatively small number, the length of the material tape will affect the pick-up of the placement machine. In the actual SMT Assembly process, the shortest length of the tape is 10cm, but this is not the industry standard. The acceptable length of each factory is different, which depends on the quality of the placement machine and feeder, as well as the material If possible, try to ask customers to provide more materials to ensure safe production.

Grande SMT Assembly Prototype Trial Production: Due to different types of feeders, too short materials tape is time-consuming and labor-intensive, the key is to explain to the customer in advance, let the customer decide whether he/she is willing to buy a few more materials, or is willing to extend the Assembly time and pay more assembly fee; BTW, the shortest material tape for PCBA Prototype Standard set by Grande is 10cm around.

The packaged material only needs to be stuck by the feeder, generally a 10cm tape is enough. However, considering the possibility of defects such as throwing materials, it is also okay to prepare a little more. After all, the 0603 materials are not too expensive.
