What is laser glue removal? It utilizes high-energy laser beams to instantly "vaporize" the adhesive layer through photothermal effects, achieving non-contact, stress free, and micrometer level precision cleaning. The entire process does not require chemical solutions and does not damage the workpiece, earning it the reputation of being a "green surgical knife" for precision manufacturing.

How to choose a suitable laser glue remover?
Choosing a laser glue remover should revolve around three core elements:
Process requirements, technical indicators, and supplier services
▼▼▼
Step 1: First, ask "clarify" your own process requirements
This is the cornerstone of selection. We suggest that you first clarify three questions:
Besides what material? Is the substrate metal, plastic, or ceramic? Is the adhesive layer made of epoxy resin, silicone, or UV glue?
What does the workpiece look like? Is it a flat surface, or are there tiny pins, deep grooves, or irregular structures?
What is the tolerance for damage? Is it allowed for slight scratches on the substrate, or must it be undamaged?
Practical case: Taking SOT723 transistor as an example, it has a small size and extremely thin solder pads, and conventional equipment is prone to electrode damage. At this point, it is necessary to use picosecond ultra short pulse lasers and cooperate with high-precision vision systems to achieve precise positioning and achieve "no damage to the substrate during adhesive removal".
Step 2: Stick to the "two core" technical indicators
After clarifying the requirements, the following key points should be emphasized when comparing devices:
▶ Core 1: Laser Type
Thermistor components (such as thin sheets or substrates with chips) → Pulse laser is preferred, as it has a very short operating time, a small heat affected zone, and is not easily damaged by surrounding materials.
Conventional and heat-resistant materials can be considered for continuous laser, which has higher efficiency and relatively lower cost.
▶ Core 2: Accuracy and Stability
Positioning accuracy: This determines whether the glue removal position deviates. The CCD automatic positioning accuracy of high-end equipment (such as Guangyue Sheng) can reach ≤ 0.01mm, and the processing accuracy is controlled within ± 30 μ m.
Long term stability: Inquire about the power attenuation of the equipment after 8 hours of continuous operation, which directly affects the yield rate and maintenance costs.
Step 3: Verify the supplier's strength through "actual testing"
No matter how good the equipment parameters are, it also depends on the actual effect and service guarantee. I suggest you do three things:
Pre sampling: This is a necessary step. Provide your real samples for on-site or remote testing by suppliers to personally verify the effectiveness and efficiency of adhesive removal.
Customization capability: Inquire with the supplier if they can adjust the optical path design or develop specialized processes based on your specific workpiece. Standard products often cannot solve all pain points.
After sales response: Clarify the warranty period, response time, and whether operational training is provided. Professional suppliers, such as Guangyue Sheng, typically prioritize process support as their core service.
