Observation of conductive particle shapes in COG implementation

Observing the state of conductive particles from the planar direction and cross-sectional direction! A case study confirming the degree of deformation.

We will introduce the observation of the shape of conductive particles in COG implementation. ICs and liquid crystal panels are implemented using the COG method with ACF (anisotropic conductive film). A resin ball is used as the core, and a metal layer (such as nickel or gold) is deposited on its surface for conductivity. During connection, the particles deform appropriately to electrically connect the IC and the panel. To confirm the degree of particle deformation and the connection state, cross-sectional observations were conducted, revealing that the amount of particle deformation was "medium," indicating an appropriate level of deformation. By examining the deformation of conductive particles from both the planar and cross-sectional perspectives, we can explore the correlation with display defects. Please feel free to contact us for any inquiries regarding panel-related issues. [Summary] ■ In implemented ICs, slight "warping" or "tilting" can cause differences in particle deformation between the edges and the center, potentially leading to display defects. ■ By examining the deformation of conductive particles from both the planar and cross-sectional perspectives, we can explore the correlation with display defects. *For more details, please refer to the PDF document or feel free to contact us.

The observation target is an IC chip connected to the LCD panel using the COG mounting method! The circuit surface was clearly visible.

We will introduce a case where precision planar grinding was applied to remove wiring and conductive particles from a glass substrate, allowing for the observation of IC chip circuits with minimal damage. Careful planar grinding was performed from the glass substrate side, removing material down to a few micrometers from the IC chip, enabling the observation of the circuit surface. The IC chip circuit surface was clearly visible, and detailed observation at high magnification became possible. There are many samples, like the one in this case, where detailed observation has become possible through planar grinding, as well as samples that can be processed using FIB or CP techniques. If you have any samples you are struggling with, please consult us. We accept requests for planar grinding only, as well as requests that include observation and analysis.

Thank you very much for visiting our company website and catalog, and for your interest in our diesel engine generators. From customer surveys, the most common feedback we received was: - I want to see the actual generators that have been installed. - I want to see them operating under real load. - I want to hear the opinions of companies that have installed them. - I want to see the generators in operation before making a purchase. After all, it’s understandable to feel worried about purchasing a generator without seeing the actual unit first, right? As the saying goes, "Seeing is believing," so we will be holding this tour. It will take place in that area of the Kanto region, where summer temperatures exceed 40°C. We successfully operated our generators this summer as well, so we are confident in handling the heat (sweat). Additionally, it has been confirmed that our generators equipped with the world-leading "Scania engine" are "fuel-efficient." This will surely help reduce daily operating costs. Please note that while we will provide kind and courteous assistance, the meeting and dispersal will be at the site (transportation costs and other expenses will be borne by the customer), so please understand this in advance.
