Carrier strip peel strength testing machineDeveloped and designed for the strip peeling test, it is used to test the peeling force of the cover tape on the carrier tape. Through a tensile tester and its transmission part, combined with software, the peeling force at various positions of the cover tape of a certain length of the carrier tape is generated into a curve of peeling force and displacement, and the test results are judged. It is controlled by a microcomputer chip and can be used for material tensile and peeling force testing. It is fully operated by a computer and has an automatic reset function. When connected to a computer, it can output test graphics and table data as the basis for material testing. Widely used in fields such as electronic packaging and semiconductor manufacturing. Its core function is to quantify the force value data of the stripping process, ensuring the reliability of the carrier tape packaging.
Working principle and testing mode:
Working principle:
The fixture fixes the carrier sample and peels off the cover tape at a set angle (usually 180 ° or 165 °~180 °) and speed, with high-precision sensors recording changes in peeling force in real time.
Combined with a microcomputer control system, automatically calculate the peel strength and generation force time curve, and determine whether the results are qualified (such as setting upper and lower limit alarm values).
Test mode: Supports 180 ° peeling (mainstream), T-shaped peeling, etc., suitable for different carrier tape specifications.
Testing process:
Sample preparation: Cut the carrier tape sample and clean the adhesive surface (such as wiping the metal plate with acetone).
Parameter settings: Fixed sample angle, set peeling speed and load range.
Run test: Start the device to automatically peel off, record the full force curve, and calculate the average peel strength using software.
Result analysis: Output maximum/minimum force values and pass judgment.
