A link ball that achieves smooth operation with minimal play.
The link ball uses high-precision bearing steel balls in the spherical part, and after forming the holder by die-casting, the shank part is specially welded. This innovative manufacturing method allows the mirror surface of the steel ball to be transferred to the spherical part of the holder, resulting in full surface contact and smooth operation with minimal clearance.
Thick paper that can attract magnet products!
●This is a composite product made by laminating steel foil with coated paperboard. ●It can be cut with scissors or a cutter. ●It is a special paperboard that magnets can adhere to. *Please note that it is not a magnet, so the product itself does not have magnetic properties.
A trackball without a ball that utilizes the world's first electromagnetic induction technology.
This is the world's first next-generation trackball utilizing electromagnetic induction. Unlike traditional mechanical and optical types, it has no contacts due to the electromagnetic induction method, preventing any intrusion of substances through gaps, and it is completely unaffected by vibrations, making it the best trackball that can be used in any harsh environment.

Cleaning ball (shower ball/clean ball)
Operating pressure: 3-7 kg/cm² Flow rate: Approximately 70-110 L/min Shooting distance: Approximately 1.5-3 m Outer diameter dimensions: Ø60×130 mm Material: SUS304, Teflon
BGA Reballing (High Volume Support)
We have started a service to reball a large number of BGAs in a short delivery time. Of course, we can accommodate even from 1 piece. Please feel free to contact us. (The photo shows a fixture for 1 piece.)
Polyethylene ball for preventing oxidation of pharmaceutical liquids
Compared to other materials (expanded PP, PE, EPDM, 2-piece balls), it does not allow other products to catch up in terms of low cost, durability, and range of use. The mold cost is also low, and products can be manufactured in the desired shape.
![Change in the composition of BGA solder from lead-free to eutectic solder [Case Study]](https://image.mono.ipros.com/public/product/image/c01/2000231267/IPROS71203217742452310542.png?w=280&h=280)
I want to change the composition from lead-free solder balls to eutectic solder balls! We will solve your concerns about solder composition changes!
In the composition change of K-All's solder, we will switch from lead-free balls to eutectic balls. If the solder specifications of the substrate and the solder balls of the BGA differ, unexpected troubles may arise. K-All also conducts work to prevent implementation troubles by removing solder with different specifications and then attaching solder balls that match the specifications. We propose a reliable method while making use of your existing BGA. 【Features】 ○ Specification change from lead-free balls to eutectic balls ○ Preventing implementation troubles in advance through composition changes ○ Proposing a highly reliable method For more details, please contact us or download the catalog.
![BGA Reballing [Presentation of technical materials for BGA reballing and rework]](https://image.mono.ipros.com/public/product/image/647/2000712771/IPROS82688767437824773084.png?w=280&h=280)
We have numerous achievements in reballing and reworking "BGA with underfill," which is highly challenging in BGA reballing and rework! Technical materials featuring case studies are currently available!
Kei-Oll has numerous achievements in reballing and reworking with high-difficulty "BGA with underfill." Additionally, we can handle a wide range of micro sizes below 5×5mm and ball pitches from 1.27mm to 0.25mm, and we are capable of reballing for irregular and special pitch arrangements. We can assist in removing and reballing devices that are hard to obtain from other boards for implementation, especially when strict deadlines need to be met. 【Features】 ■ Two types of reballing technology (Capable of ball mounting using cream solder printing methods and dedicated flux application methods) ■ Supports micro-sized packages down to 5×5mm ■ Can accommodate changes in solder conditions (Composition changes from lead-free solder to eutectic solder are also possible) ■ Supports a wide range of pitches, including special pitches (Capable of handling ball pitches from 1.27mm to 0.25mm) *For details, please download the PDF or contact us.
Top ball - A linear motion mechanism utilizing the rolling motion of a ball.
【High Load Capacity and Long Lifespan】 The ball contact raceway surface of the load plate is precisely ground in a circular arc shape. As a result, it has approximately three times the load capacity and about 27 times the lifespan compared to conventional products. 【Self-Aligning Capability】 The load plate is thicker in the center and thinner at both ends, allowing for self-aligning movement around the central part, which absorbs machining and installation errors between the housing and the shaft. 【Floating Seal】 The floating seal utilizes the self-aligning feature of the NB top ball, allowing it to smoothly follow the shaft even when there is eccentricity in the outer and inner diameters of both end faces. Additionally, there is no change in overall length with or without the seal, enabling a compact design. 【High-Speed Compatibility】 The NB top ball is a product that enables excellent high-speed performance. It can be used at motion speeds of up to 180 m/min. 【Gap Adjustment】 The load plate is assembled in a free state within a resin outer cylinder. By incorporating it into a housing for gap adjustment, it allows for the adjustment of the gap between the ball and the shaft. 【Top Ball Unit】 The top ball unit is designed with appropriate dimensions for the inner diameter of the housing, maximizing the features of the top ball.
