Splicing tape Production standard

Production standard
1. Appearance quality standard
Joint smoothness: The joint should be flat, without obvious bumps, wrinkles or warping.
No air bubbles or impurities: There should be no air bubbles, foreign objects or glue residue in the joint.
Edge alignment: The edges of the two sections of tape should be aligned, the width is the same, and the deviation is usually not more than ±0.1mm.
Uniform tape coverage: If the receiving tape is used, the tape should completely cover the joint, and there is no offset or leakage.
2. Dimensional accuracy standard
Width consistency: the width of the material belt at the seam should be consistent with the raw material belt, and the deviation should not exceed ±0.1mm.
Thickness consistency: The thickness of the joint should be consistent with the raw material belt, avoid being too thick or too thin, usually the deviation does not exceed ±0.05mm.
Length error: the total length after feeding should meet the requirements, and the error is controlled within ±1mm.
3. Mechanical performance standards
Tensile strength: The tensile strength at the joint should reach more than 90% of the raw material belt to ensure that it will not break during the production process.
Flexibility: The joint should have a certain degree of flexibility and be able to withstand a certain amount of bending and stretching without cracking.
Peel strength: If the tape is used to connect, the peel strength between the tape and the material should meet the requirements, usually not less than 2N/mm.
4. Electrical performance standards (if applicable)
Electrical conductivity: If the tape is used for electronic components, the resistance at the joint should be consistent with the raw material tape, with a deviation of not more than ±5%.
Insulation: If the tape needs insulation, there should be no leakage or short circuit at the joint.
5. Environmental adaptability standards
Temperature resistance: The joint should be able to withstand temperature changes in the production environment, usually requiring no failure within a certain temperature range (such as -20 ° C to 80 ° C).
Moisture resistance: The joint should have a certain moisture resistance to avoid opening or failure in a high humidity environment.
Chemical resistance: If the tape comes into contact with chemicals, the joints should be resistant to chemical corrosion.
6. Process consistency standard
Connection position: The connection position should meet the process requirements and avoid connection in key areas (such as the location of precision components).
Receiving length: the length of the receiving belt should meet the production requirements to avoid too long or too short affecting the production efficiency.
Frequency of connection: minimize the number of connection times to avoid frequent connection affecting the overall quality of the material belt.
7. Reliability test standards
Tensile test: Tensile test is performed on the joint to ensure that it can withstand the tension during the production process.
Bending test: Perform multiple bending tests on the joint to ensure that it does not crack or fail.
Burn-in test: Simulate a long time use environment to test the durability of joints.
8. Record and traceability standards
Receiving records: record receiving time, operator, materials and tools used for easy traceability.
Quality inspection record: record the quality inspection results of each receiving material, including appearance, size, strength and other data.
9. Safety and environmental standards
Material environmental protection: Bonding tape and glue should meet environmental requirements and do not contain harmful substances (such as RoHS standards).
Operation safety: Tools and materials used in the feeding process should meet safety standards to avoid injury to operators.
