![DSV501M vs. Coin Size Comparison]()
In the backend process of semiconductor manufacturing, die bonders and wire bonders are essential for chip packaging. As chips become increasingly miniaturized and packaging efficiency improves, industrial cameras must meet higher standards—not just functional adequacy, but extreme performance compatibility. Key metrics now include ultra-compact size, lightweight design, and high-speed responsiveness. Traditional industrial cameras, hindered by bulky dimensions, excessive weight, and limited dynamic performance, struggle to integrate with fast-moving robotic arms or confined spaces, significantly limiting packaging precision and throughput.
To meet these evolving demands, Do3Think has introduced the DSV series ultra-compact industrial cameras (models DSV501/DSV501M). Featuring a remarkably small size 20mm ×20mm×22mm, a featherlight 16g weight, a high frame rate of 60 FPS, and microsecond-level exposure capabilities, this camera series delivers a groundbreaking solution for the semiconductor packaging industry.
Limitations of Traditional Solutions: the trade-off between size, weight, and performance
In die bonder positioning systems, industrial cameras must be mounted on high-speed placement heads to capture real-time deviations between die and substrate, feeding data to the motion control system.
Traditional setups face three critical challenges:
- Space Constraints: Tight mechanical designs inside equipment make it difficult to install standard-sized industrial cameras.
- Dynamic Stability: Heavier industrial cameras increase inertia on robotic arms, reducing positioning accuracy during rapid start-stop movements.
- Performance Compromises: To reduce size, some manufacturers sacrifice resolution or frame rate, failing to meet micron-level precision requirements.
For instance, in testing conducted by a leading global semiconductor equipment manufacturer, traditional industrial cameras caused a 30% increase in placement head vibration due to excess weight. This lead to a die placement deviation rate of 0.5%, well above the 0.1% process requirement. High power consumption leads to heat issues, further reducing the reliability of continuous device operation.
Technology Advantages: Miniaturized Design Meets High Performance
The Do3Think DSV industrial cameras overcomes these issues through innovations in sensor selection, circuit design, and mechanical structure:
Sensor & Optical Design
High resolution at high speed: Built on Onsemi sensors, the camera supports full-resolution output at 2568×1920 @ 60 FPS. Frame rates can reach up to 219 FPS using ROI (Region of Interest), ensuring real-time imaging during rapid motion.
Color & Mono: DSV501 response spectrum 390nm~650nm; DSV501M extends to 380nm~940nm, adapting to the multi-light source environment in semiconductor packaging.
Compact Structure & Optimized Circuitry
Ultra-compact design: Through high-density circuit layout and integration with M12 lens mount reduce the device to 1/5 the size of conventional industrial cameras, with a total weight of only 16g, comparable to a coin. This significantly reduces robotic arm load.
Low power consumption, Wide Temperature Range: Power consumption <1.2W (standby <0.5W), supporting ambient temperatures from -10°C to 50°C. Low heat generation minimizes image noise during long-term use.
Hardware-Software Co-Optimization
Real-Time FPGA Processing: Built-in hardware acceleration supports dynamic noise reduction and microsecond-level exposure, preserving image clarity in high-speed environments.
Multi-trigger mode: supports hardware trigger (TTL-5V) and flash synchronization (FLASH output), accurately matching the bonding machine placement rhythm.
Application Highlight: Precision Positioning in Die Bonder Systems
A global semiconductor equipment manufacturer recently upgraded its die bonder vision system with the DSV501 industrial cameras, achieving remarkable improvements:
The camera was directly embedded into a pre-reserved 20mm × 20mm cavity in the placement head—no mechanical modifications needed.
Weight was reduced by 70%, lowering vibration amplitude to under 5μm. Die placement deviation rate was stabilized at 0.08%. In 72-hour continuous production line testing, the camera maintained full performance with no overheating or frame loss, and a false detection rate under 0.01%. Its wide temperature design ensured stable function both in controlled cleanroom environments (25°C) and in Southeast Asian factories operating at 40°C.
Beyond semiconductor packaging,the DSV series coin industrial camera is also ideal for other high-performance, space-constrained scenarios such as:
- Electronics Manufacturing: Precision inspection of component assembly and appearance.
- Medical Devices: Fine assembly and inspection in medical equipment manufacturing.
- Automated Assembly: Part positioning and dimensional measurement in automation lines.
The success of Do3Think’s DSV series is not just a leap in technical specifications—it marks a shift in industrial vision systems from “functional implementation” to“extreme scenario adaptability.” As 5G, AI, and edge computing continue to converge, ultra-compact cameras like the DSV will quietly—but critically—empower the smart factories of the future as invisible vision enablers.
