The exhibition has come to a successful conclusion, and we look forward to meeting you again next time!

From July 11th to 13th, Vision China 2023 was successfully held at the National Exhibition and Convention Center (Shanghai). CST brought a variety of visual products and wonderful cases to the exhibition, and the three-day exhibition ended successfully in the afternoon of the 13th.

01Review of wonderful cases

For key industries such as semiconductors and photovoltaics, we demonstrated multiple imaging solutions on site, including battery cell PL detection, silicon wafer hidden crack detection, time-sharing line scanning controller, full-spectrum light source, 50 million LUX fiber optic light source, lithium battery solder detection, magnetic core appearance detection, as well as full-defect time-sharing line scanning lighting system and programmable controller.

CST 50 million LUX fiber optic light source

Product model:CST-HLS250-LEP;
Light source illumination ≥50000Klux, life span 12000h (L70);
Equipped with a 5-pack filter converter, you can change the light color by switching filters through the LCD touch screen or host computer software;
The light source brightness control adopts constant current method, 1000-level dimming, accurate and stable.

It is suitable for various inspection projects with high requirements on light source brightness, especially wafer inspection in the semiconductor industry.

CST Full Spectrum Light Source

Product model: CST-HLS150-W;
The light source spectrum covers a range of 350nm-2500nm and can be used with filters;
Illuminance ≥2000Klux;
A variety of standard interfaces, hoses, beam diameter specifications and double-tube optical fibers can be customized.

It has a wide spectrum coverage and high brightness, and is used with optical fiber and filters. It is mostly used in the semiconductor industry, such as wafer chip positioning detection, etc.

CST core appearance inspection

Detect appearance defects such as core chipping, cracks, holes, and residual edges;
The project customized dual-color AOI light source achieves the best imaging effect by combining two optimal light source irradiation angles;
Use color cameras with red and blue dual-color imaging to improve defect contrast;
Use with strobe controller to increase light source brightness and improve detection efficiency.

CST Cell PL Testing

Light source model: CST-LS300-LD808;
808nm laser light source combined with linear array industrial camera for imaging;
Light source wavelength 808±5nm, wavelength-temperature coefficient 0.3nm/℃, peak power (CW): 80W;
Photoluminescence (PL) principle is used to detect hidden cracks, which is non-contact and not prone to secondary defects.
Suitable for detecting hidden cracks in silicon cell after silk screen printing process.

CST Programmable Controller

Product model: CST-CPL2496C-8TD;
It can control the conduction status of all connected light sources according to the preset logic sequence;
Compared with serial port or Ethernet communication control, the light source has a faster response speed;
One IO port can control all light source channels;
The control logic of the light source can be set by the host computer through RS232.

It is suitable for scenes where there is insufficient external trigger signal but multiple light sources need to be lit simultaneously/sequentially, scenes where the brightness of light sources needs to be changed frequently during operation, scenes where multi-channel interlaced combination is required to trigger light sources, etc.

The imaging solutions we demonstrated were highly praised by the audience and attracted the attention of many potential customers and partners.

02 On-site review

At the exhibition, our professional team, with rich industry experience and expertise, conducted in-depth discussions with many customers and provided customers with personalized answers and technical consultations. The audience was impressed by our team's professionalism and thoughtful service, and expressed high praise and trust in our company.

The successful conclusion of the exhibition is not only the result of our team's hard work and active cooperation, but also a reflection of our in-depth understanding of the market. During the exhibition, we not only displayed imaging cases, but more importantly, we had extensive exchanges and interactions with the audience and industry peers.

We listen to their needs and feedback to further optimize the performance of our products and ensure that we can better meet the needs of the market. We firmly believe that through continuous efforts, we will achieve even more brilliant achievements in the field of machine vision. The curtain has not fallen, CST looks forward to seeing you next time!
