[Seminar] Waterproof Design [Advanced] - Waterproof Structures and Design in Electronic Devices -
For designers at a standstill. Overcome that wall with "gel waterproofing" and "design value guidance." Learn the secrets of waterproof design in 3 hours [Advanced Edition].
For those struggling to find solutions in waterproof structural design, For those who have completed our 【Beginner's】【Intermediate】 courses, For managers who want to establish more advanced and reliable waterproof design techniques as a company (targeting experienced individuals who regularly consider waterproof structures), "I've exhausted standard methods, but there are still areas I just can't resolve..." "What is the optimal compression rate for this sealing groove?" Building on the foundational knowledge learned in the beginner and intermediate courses, we will explain more detailed design methods and advanced techniques that are rarely seen elsewhere. In the seminar, in addition to "design guidance" on specific dimension determination and specification considerations for gaskets and double-sided tape, we will thoroughly explain gel waterproofing, which is gaining attention as a "super technique" for structurally challenging areas. We will also cover special cases such as insert molding of different materials and the design of undulating parts (2.5D). Additionally, we will share specific issues that arose during prototype evaluation, such as cap air leaks and NG cases in panel tape waterproofing, along with their solutions.

Applications/Examples of results
You can obtain specific solutions to problems that are at a standstill. You will learn an advanced technique called "gel waterproofing," which is one way to address structurally problematic areas. You can learn methods to deal with issues such as water ingress or air leaks that result in failure during prototype evaluation. You will acquire a concrete, data-driven design methodology. You will learn detailed methods for determining the dimensions of waterproof components and various parts of the housing, which have been difficult to find until now. You will receive guidance on specific design values, such as "compression ratio/filling ratio" in gasket and packing seal groove design. You can learn from actual failure cases to prevent troubles before they occur. You can learn about specific defect cases, such as "cap air leak failure cases" and "cautions and failure cases during panel (tape waterproofing)," along with their solutions. You will acquire advanced design techniques for special conditions. You will learn design methodologies that address special and high-difficulty situations, such as "undulating part design (2.5D)" and "design during insert molding of dissimilar materials."

Company information
A Challenge to Transform "Impossible" into "Possible" in Design Quality One day, we received a development project for a new wearable device that pursued unprecedented thinness and lightness. The client's request was, "It must be completely waterproof while not compromising on design at all." The project initially ran aground due to this conflicting challenge. The thickness of the casing was just a few millimeters. With conventional waterproofing technology, it was not only difficult to protect the internal precision instruments but also to maintain design integrity. While many engineers threw in the towel, declaring it "impossible," the challenge at Kamigami Corporation began. Our team first thoroughly utilized 3D data as part of our DX promotion, repeatedly conducting simulations in a virtual space. This was a crucial process to eliminate rework and improve development productivity. Drawing on the experience and insights that our representative, Suzuki, had cultivated over many years in developing some of the world's thinnest waterproof designs for smartphones, we meticulously analyzed every possible water intrusion route, leaving no 0.1 millimeter gap unchecked. We pursued the highest design quality and devised a new waterproof structure that overturned conventional wisdom.
