Application of Automatic Dispensing Machines in Chip Bonding Dispensing: The PCB chip bonding dispensing technology refers to the use of specialized adhesive to bond various functional chips onto a PCB circuit board. The automatic dispensing machine not only provides the function of securing the chips onto the PCB, but also enhances the stability of the assembly. This technology can improve the data transmission bandwidth between chips. Okata Intelligent Technology Co., Ltd will provide you with a detailed explanation!
With the continuous advancement of electronic modernization, the quality and transmission speed of chips in China have also been steadily and rapidly improving. If chip bonding onto PCB electronic boards can be stably achieved through dispensing technology, it will make a significant contribution to the modernization process. The question is: how can chips be accurately bonded onto PCB boards?
Application of automatic dispensing machines in chip bonding dispensing?
We all know that the chip is the "heart" of every device, representing the crystallization of advanced technology. Therefore, errors during adhesive dispensing are unacceptable. Traditional manual dispensing methods are clearly inadequate to meet these technical requirements.
Here, we recommend using an automatic dispensing machine for adhesive application. Such a machine can precisely control the dispensing path, speed, and adhesive volume, thereby avoiding issues such as adhesive overflow or uneven droplet distribution.
An automatic dispensing machine not only ensures high-precision dispensing but also allows customized dispensing paths. Furthermore, when using adhesives in different colors, it can create patterned dispensing with enhanced visual aesthetics.
Okata Intelligent Technology explains how to select dispensing needles for automatic dispensing machines
Principles for selecting dispensing needles based on dot size:
- For small dispensing dots → use small needles, low pressure.
- For large dots within a short time → use large needles, high pressure.
- For long-duration dispensing of viscous adhesives → use angled needles, high pressure.
- For water-based fluids with timed dispensing → use small needles, low pressure, with settings adjusted as required.
Influence of adhesive type on needle selection:
In the dispensing industry, adhesive characteristics significantly affect needle selection. The following five special adhesives require particular attention:
- UV Adhesives → use amber syringes, white pistons, and angled UV dispensing needles.
- Anaerobic Adhesives → use 10CC syringes with standard white PE pistons.
- Light-curing Adhesives → use black opaque syringes with white pistons to block UV exposure.
- Cyanoacrylate Adhesives:
+ For water-based CA → use safety pistons and Teflon-lined metal needles.
+ For viscous CA → use tapered needles.
+ For flexible application → use PP needles.
- Sealants and paste-like fluids → recommended to use safety pistons with angled needles.
