Before receiving the new SMT mounter machine ready to go online, where should customers prepare? First of all, the new SMT mounter machine must first be checked and tested. Although SMT equipment suppliers will debug the placement machine before the product leaves the factory, for safety and better work, the main indicators should be tested on the placement machine. So, what kind of index does the customer need to test on the new SMT mounter machine?
1. The types, specifications, placement direction, substrate size, and placement range of the originals that can be mounted on the SMT mounter machine conform to the specification standards.
2. Mounting speed of SMT mounter machine: CPH mounting rate tested with 1608 chip components is not less than 60% of the nominal IPC9850 speed, or the SPC speed is not more than 2 times the nominal speed;
3. Chip losing rate: not more than three thousandths.
1. The various indicators, buttons and operating handles of SMT mounter machine have a complete appearance, and the operation and display are normal;
2. The computer system is working normally;
3. The input and output system of the SMT mounter machine works normally.
1. All conveying belts, chains, connecting pins and rods are complete, and there is no aging damage;
2. The transmission guide rails and lead screws of SMT mounter machine run smoothly and coordinately, without abnormal noise and oil leakage.
1. SMT mounter machine drives the cylinder, solenoid valve, piping, and connection head without any foreign matter blockage, no loose air leakage. The drive cylinder and solenoid valve work normally without noise;
2. The compressed air drying and filtering device is complete and intact;
3. The vacuum degree of the SMT mounter machine head is not less than 500mmHg. The placement accuracy is the maximum deviation between the center of the component and the center line of the corresponding pad, which does not exceed 1/3 of the width of the component solder foot (visual inspection); or the occurrence rate of abnormal deviation is not more than three thousandths.
The SMT mounter machine an intact appearance, accurate instructions, eye-catching readings, and is within the qualified period of use; the inside and outside of the equipment are regularly maintained, kept clean, free of oil and corrosion, the surrounding accessories are arranged in an orderly manner, and the equipment is well lubricated.
