 | Dingchang has introduced: 2 units of ALeader 7710D Functions: It is an international high-speed in-line AOI, equipped with high-speed intelligent cameras and a new generation of light source system. The images are more delicate and the detection speed is faster, which is 40% faster than the previous generation products. It can effectively meet the requirements of international high-speed production lines. In order to solve the problem that irregularly shaped boards cannot accurately reach the loading position, it can be used in multiple positions such as after printing, before the furnace, and after the furnace, serving multiple purposes with one machine. Main Detection Contents: Solder Paste Printing: Presence or absence, misalignment, insufficient solder, excessive solder, open circuit, bridging, contamination, etc. Component Defects: Missing components, misalignment, skew, tombstoning, side standing, flipped components, wrong components (OCV), damage, reverse installation, etc. Soldering Point Defects: Excessive solder, insufficient solder, cold soldering, bridging, copper foil contamination, etc. |
| Dingchang has introduced: 10 units of VCTA-A410 inspection instruments Functions: AOI conducts mechanical vision inspection on electronic components such as PCBs to ensure that the components of PCBA are in the correct position and are soldered correctly. Generally, for manual visual inspection operations before and after the SMT furnace, some manufacturers may omit the AOI operation before the furnace. Automatic Optical Inspection (AOI) is an intelligent visual inspection of the production of printed circuit boards. All catastrophic failures (such as component breakage) and quality failures can be automatically scanned by sensors. It is practically helpful for improving the durability of circuit boards PCB and PCBA. Main Detection Contents: Solder Paste Printing: Presence or absence, skew, insufficient or excessive solder, open circuit, contamination; Component Defects: Missing components, misalignment, skew, tombstoning, side standing, flipped components, reverse polarity, wrong components, damage; Soldering Point Defects: Excessive solder, insufficient solder, bridging; Wave Soldering Detection: Insufficient solder, excessive solder, soldering point bridging or short circuit, cold soldering, voids. |
| Dingchang has introduced: 2 units of X-RAY non-destructive perspective inspection instruments Functions: It is used for the quality inspection of BGA, CSP, flip chip, the interior of semiconductors, and multi-layer circuit boards, as well as the inspection after rework. ELT's unique image inspection technology enables very accurate judgment of cold soldering. Main Detection Contents: Welding condition of the PCB board Detection of short circuits, open circuits, voids, and cold soldering IC packaging inspection Inspection of components such as capacitors and resistors Internal flaw detection of electric heating tubes, lithium batteries, pearls, precision devices, etc. Internal flaw detection of some metal devices |
| Dingchang has introduced: 2 units of Intelligent First Article Inspection Instrument, Efficiency E680 Functions: For the PCBA to be subjected to the first article inspection, the inspection program is automatically generated by integrating the BOM list, coordinates, and the high-definition scanned image of the first article. It can quickly and accurately detect components, automatically determine the results, and generate a first article report, achieving the purpose of improving production efficiency and accuracy, and enhancing quality control at the same time. Actual Measurement Results: Since the intelligent first article inspection instrument was put into use last year, the production line has submitted the first articles for inspection more than 4,000 times. The intelligent first article inspection instrument has detected about 30 errors in the first articles, with a detection error rate of 100%. It has successfully prevented batch quality incidents caused by errors in the first articles. |
| Manual Visual Inspection Functions: Conduct manual visual inspection on the detection area of the PCB circuit board, which depends entirely on the experience of the workers. Actual Measurement Results: After the first PCBA is mounted, inspect the position of the components to check whether they are correctly placed. It can detect issues such as missing component installation, wrong polarity, bridging, and some cold soldering situations. |
