We have substrate cleaning machines and ultrasonic cleaning machines, so we can achieve precise cleaning according to your needs, including flux removal and fine dirt on substrate surfaces and components!
While I believe there are many cases of substrate mounting using no-clean paste, cleaning has become essential to ensure high reliability. Our company has extensive experience in substrate cleaning for various prototype and mass production assemblies, and we have received great acclaim from many customers. We use IPA (isopropyl alcohol) and environmentally friendly hydrocarbon and glycol-based cleaning solutions to remove flux adhered to the substrate. We propose the optimal cleaning method considering the condition of the mounted components and flux, using techniques such as ultrasonic cleaning, electric brushing cleaning, and manual finishing cleaning, and we are flexible in responding to customer requests. If you are concerned about the cleanliness of the flux and wonder how well it can be cleaned, we also conduct free test cleaning for one unit (up to three units total) using each method. * If it is not RoHS compliant (such as eutectic), only manual finishing cleaning will be available. * Please note that free test cleaning may incur charges for small order quantities, so please consult with us first.

basic information
【Cleaning Equipment】 - Ultrasonic Cleaner / Chiyoda Electric / IK-204 - Ultrasonic Cleaner / KAIJO / CA64801 - Circuit Board Cleaning Machine / Mounting Support Group Why is flux necessary for soldering in the first place? Flux helps make soldering easier by dissolving and removing the oxide film on the metal surfaces of the circuit board pads, component electrodes, and lead terminals. Therefore: - It improves the wetting and spreading of solder. - It covers the surface of the melted solder to prevent re-oxidation. These are the main functions of flux. So, why is it necessary to clean that flux? - There is a risk of losing electrical reliability due to the occurrence of ion migration. - If the residue contains conductive materials, it may lead to leakage failures and loss of insulation. - In resin encapsulation, such as molding, it may hinder adhesion. - The appearance when customers receive the product (especially for exterior parts) may be poor. Due to these reasons, the demand for flux cleaning has been increasing recently.

Company information
Our company was established with the aim of contributing to further technological development in the timeless technique of "soldering" through printed circuit board assembly. "We are a company that can solve your problems" and "a company that can reach those hard-to-reach places" – that is Aikei Electronics. Our printed circuit board assembly services cater to both prototypes and mass production, responding to requests starting from just one unit, and we also accept spot work. The transition to mass production can be made swiftly thanks to our flexible production system and reliable technical skills developed from prototypes. For example, if you are facing challenges such as "it's difficult to secure hand soldering technicians in-house," "ensuring quality in hand soldering is tough due to miniaturization of components," "I'm concerned about flux contamination, but I wonder how clean it will be after washing," "we can't accommodate sudden increases in production on our in-house mass production line," or "other companies are reluctant to take on such requests," please feel free to consult with us. Our company is based in the Mikawa region of Aichi Prefecture, conveniently located 20 minutes from Toyokawa IC on the Tomei Expressway and 10 minutes from Shinshiro IC on the New Tomei Expressway, allowing for quick access to Nagoya and Hamamatsu City in Shizuoka Prefecture, as well as other areas. We mainly serve the Tokai region but can also accommodate requests from Kansai, Kanto, and other regions.
