ときわ電子材料 List of Products and Services

We would like to introduce a case where we designed and manufactured a tape pressure fixture. It is capable of applying pressure to three types of workpieces with different heights in a single operation. The design took into consideration the rigidity of the frame, measures to prevent damage to the workpieces, and ease of operation. [Points of ingenuity during processing / Technically challenging aspects] ■ Design: The design considered the rigidity of the frame, measures to prevent damage to the workpieces, and ease of operation. *For more details, please refer to the PDF document or feel free to contact us.

• Processing Jig

We would like to introduce a case of designing and manufacturing a rubber bush pressing device at our company. The X, Y, and Z coordinates and angles of the hand section are adjustable. The Φ2 pin of the central pallet fits into the Φ2.1 hole of the chuck. It can automatically press in and align 100 bushes in about 3 minutes. Please feel free to contact us if you have any inquiries. [Points of ingenuity during processing / Technically challenging aspects] ■ Assembly: Adjustment of the X, Y, and Z coordinates and angles of the hand section. The Φ2 pin of the central pallet (brown) fits into the Φ2.1 hole of the chuck (40 locations). ■ Design: Created from a jig, and since the manual jig worked well, it was turned into a device. *For more details, please refer to the PDF document or feel free to contact us.

• Processing Jig

We would like to introduce a case of designing and manufacturing a sulfuric acid cleaning holder at our company. The work support part is designed to prevent liquid from pooling. To submerge in sulfuric acid, we use materials that do not dissolve, and we have angled various parts to improve the flow of sulfuric acid. [Points of ingenuity during processing / Technically challenging aspects] ■ Assembly: If the PFA screw is tightened too much, the screw head can break off. ■ Design: Since processing of 3D shapes is possible, the work support part is designed to prevent liquid from pooling. *For more details, please refer to the PDF document or feel free to contact us.

• Mechanical Design

We would like to introduce a case where we designed and manufactured a circuit board inspection fixture. It allows for continuity testing on the back side while avoiding components already mounted on the front. We adopted standard parts and modified them where necessary, ensuring functionality with minimal components. [Points of ingenuity during processing / Technically challenging aspects] ■ Processing: Set processing conditions to ensure the accuracy of the holes for inserting probes and to prevent burning. ■ Assembly: It has four layers, and if the coordinates of each layer are not accurately aligned, it will not operate smoothly due to interference. ■ Design: We adopted standard parts and modified them where necessary, ensuring functionality with minimal components. *For more details, please refer to the PDF document or feel free to contact us.

• Inspection fixture

We would like to introduce a case where we designed and manufactured a code set inspection fixture. It is possible to simultaneously inspect the continuity of six bundled wires.

• Inspection fixture

We would like to introduce a case study of the design and manufacturing of flow pallets at our company. During the automatic soldering of electronic components mounted on printed circuit boards, it is possible to protect areas other than the openings. To prevent the circuit board from lifting, it is designed to be securely held down with simple operations. [Points of ingenuity during processing / Technically challenging aspects] ■ Processing: Due to the high wear of the tools on the material, processing conditions were set to prevent changes in tool diameter from affecting precision. ■ Design: Focused on making it as compact as possible while ensuring it does not lack strength. *For more details, please refer to the PDF document or feel free to contact us.

The "Flow Palette" is used during the automatic soldering of electronic components mounted on printed circuit boards. Due to the high density of the circuit boards, there are many soldering points, and when there are electronic components already mounted on the soldering surface, protection for those components is necessary. This product is effective in that situation, protecting the previously mounted components from the heat of the solder and automatically soldering the soldering points. 【Benefits】 ■ Reduction of masking labor ■ Prevention of mistakes due to human error ■ Reduction of burden on the circuit board ■ Prevention of component drop *For more details, please refer to the PDF document or feel free to contact us.
