【Small Lot Short Delivery Prototype to Mass Production】 Quick response to prototype assembly and PCB assembly is our commitment and strength. Prototype PCB assembly requires short delivery times when there is little time before the deadline. Thanks to our extensive experience in prototype PCB assembly, we can achieve same-day response from assembly to shipment. Transitioning to mass production can be done swiftly due to our flexible production system and solid technical skills developed from prototypes. Regarding requests, we can handle not only small lot mass production but also spot work such as prototypes and component replacements starting from just one unit. If you are facing issues like not having enough time for PCB assembly, sudden increases in production that cannot be accommodated by in-house mass production lines, or difficulties getting other companies to accept your requests, please feel free to consult with us! We will respond as urgently as possible.

【Circuit Board Assembly (Automatic Mounting)】 The automatic mounting machine (mounter) sets electronic component reels in dedicated feeders (feeding devices), and after suctioning the components with nozzles built into the mounting machine, it can accurately place them at pre-programmed coordinate positions. Our equipment has eight suction nozzles, and the machine can set multiple components, allowing it to continuously suction various components and mount them. This enables significantly faster and more precise placement compared to manual mounting. Additionally, the mounting machine is equipped with a component recognition camera, which can detect discrepancies in size or orientation for chip components, as well as variations in shape, lead count, and pitch for IC components through image inspection before mounting, thereby preventing misplacement in advance.

Hand Placement Assembly Hand placement assembly is the process of manually placing components on a printed circuit board that has been solder printed (compatible with manual printing) without the use of machinery. It is recommended for small lot products such as prototypes and cases where components are often in tape cut or loose form. At our company, we can accurately hand place narrow-pitch connectors, ICs, and the increasingly popular 0603 size chips while looking through a microscope, which helps prevent issues such as IC lead shorts and chip manhattans that can occur after reflow. This has received great acclaim from many customers, and we take pride in it as one of our strengths.

【Detailed Techniques and Manual Work (Hand Soldering)】 We use solder wire suitable for the task and solder electronic components onto the circuit board with a soldering iron. The selection of the soldering iron tip and temperature conditions are extremely important for soldering. If the temperature or heat transfer is poor, the solder will not melt, making soldering impossible. Conversely, if the temperature conditions are too high, the flux within the solder wire can vaporize at the tip, making it difficult to solder properly, and in the worst case, it may damage the components. At our company, we measure the tip temperature with a soldering iron thermometer before starting work, ensuring that we implement it under appropriate temperature conditions. We are also skilled at soldering challenging components such as 0603 size chips and connectors with narrow lead pitches. Sometimes, we skillfully use two soldering irons to replace components like chips and SOPs. Our certified technicians achieve precise soldering while observing through a stereo microscope. We have a variety of soldering iron tips available according to the task and purpose. Choosing the right soldering iron tip for soldering work is crucial, and we change the tips based on the target object, work, and purpose.

【Appearance Inspection Machine (AOI)】 The appearance inspection machine takes sequential photographs of the mounted circuit board using an upper camera and automatically determines OK or NG based on pre-programmed "thresholds." The main inspection items it evaluates include: - Components - Polarity - Open circuits - Shorts (bridges) Our company's AOI is equipped with a diagonal camera, making it easier to detect issues compared to standard AOIs that only have an upper camera, thus contributing to improved quality.
-
【Visual Microscopy Inspection】 In visual microscopy inspection, we use magnifying glasses, stereo microscopes, and 3D visual inspection microscopes to visually confirm and assess solderability and other aspects that are difficult to verify with AOI. The main inspection items include: - The shape and condition of fillets - Presence of solder balls - Cracks and pinholes in solder - Scratches and dirt on substrates and components Our company conducts verification work at magnifications ranging from 3x to 45x, depending on the inspection items and applications. Additionally, while we prioritize customer requests and standards for our judgment criteria, we have established our own quality standards based on IPC standards for your peace of mind, even if there are no specific requests.

【Hybrid IC (HIC) Implementation】 About Hybrid IC (HIC) We carry out the entire process from substrate mounting to automatic lead frame attachment, molding, and silk printing. For molding, we use epoxy paint for electronics, and since it is coated by machine, the finish is beautiful. In silk printing, we use a pad transfer method with machines, allowing for high-quality printing even on uneven surfaces that are impossible with inkjet methods.

**[Board Cleaning]** Our company possesses board cleaning machines and ultrasonic cleaning machines, so we can perform flux removal cleaning as requested. Why is flux necessary for soldering in the first place? Flux helps to make soldering easier by dissolving and removing the oxide film on the metal surfaces of the board lands, component electrodes, and lead terminals. Therefore, it: - Improves the wetting and spreading of solder. - 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 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 items) may be poor. Due to these reasons, the demand for flux cleaning has been increasing recently. Our company has extensive experience in board cleaning for various prototype and mass production assemblies, and we have received high praise from many customers.
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.
