ケイ・オール List of Products and Services

For the implementation of special substrates and components for which no spares can be prepared, prior arrangements are extremely important. We propose suitable solutions regarding temperature conditions and implementation methods. In particular, we have accumulated know-how on profiles suitable for various types of substrates. Leave the implementation of difficult substrates, such as high-layer, high-current substrates, flexible substrates, and aluminum substrates, to us. 【Examples】 ■ Struggling with the implementation of thick substrates ■ Wanting to implement on an extra-large substrate (external dimensions 1m square) that cannot be fed into a reflow or mounter *For more details, please refer to the PDF materials or feel free to contact us.

With over 30 years of experience in the industry, K-All has consistently been involved in PCB assembly and has numerous achievements in reballing and reworking high-difficulty "underfill BGA." We provide a clear explanation of the fundamental knowledge of PCB assembly! We explain various terms, including "BGA," "CSP," "spectroscopic analysis equipment," "Vickers hardness," and "flow characteristics." We encourage you to read it. **Contents (partial)** ■ ABC: BGA/CSP/DIP/IPC standards/JIS standards/LGA ■ A section: Printability/Whisker/Wafer Level CSP/Liquid Phase Line Temperature ■ K section: PCB cleaning/Capillary Ball/Aggregation Force/Eutectic Solder ■ S section: Side Ball/Oxides/Initial Wettability/Squeegee ■ T section: Heat Resistance/Chip Stand/Claw/De-wetting/Dispenser ■ N section: Lead-free/Wettability/Adhesive Retention Time *For more details, please refer to the PDF document or feel free to contact us.*

Kei-Oll's special substrate mounting supports difficult-to-specify substrate implementations such as high-layer, high-current substrates, flexible substrates, and aluminum substrates. For the mounting of special substrates and components for which spares cannot be prepared, prior arrangements are extremely important. We will propose optimal solutions regarding temperature conditions and mounting methods. In particular, we have accumulated know-how on profiles suitable for various types of substrates. 【Features】 ○ Special substrates are our specialty! ○ Supports various substrates → Multi-layer substrates, aluminum core substrates, large substrates, thick substrates, thin substrates, irregularly shaped substrates, etc. ○ Adequate and safe profiles with abundant know-how ○ Proposes optimal solutions regarding temperature conditions and mounting methods For more details, please contact us or download the catalog.
