SMD carrier tape is a kind of ribbon product used in the field of electronic packaging. What are the methods of choosing SMD carrier and the purpose of punching holes?

1、 Method of selecting SMD carrier tape

After determining the subscript of the carrier band, select the corresponding carrier band width according to the size and placement direction of the device.

Judge whether the device is sensitive to static electricity, and select the carrier material according to the device type.

SMD carrier tape is selected by calculating the length of carrier tape according to the number of packages per roll.

According to the model and environmental conditions, the tensile strength, accuracy, temperature tolerance and other performance parameters of the carrier belt are selected.

2、 Purpose of SMD carrier tape drilling

Some products produce vacuum after packaging due to shape and other reasons, resulting in bonding with SMD carrier tape, which makes the products unable to absorb, so it is necessary to punch holes for exhaust.

It is convenient to see whether there are encapsulated products inside the SMD carrier belt to avoid omission.
