Our proven service in Tail Spend Management and Procurement Agency means: • Taking care of finding the best value options for your supplier tail. • One partner to take care of all your non-strategic purchases, with all certifications needed • Working as your Procurement Agency for strategic parts with non-certified suppliers

At Cherrytech we recognise that in the dynamic business environment in which we operate, an effective and efficient supply chain process is critical to the success of a company and its customers. From the initial prototyping stages and throughout the complete product life cycle, we work closely with our customers to ensure we have the optimal supply chain solutions in place for each stage of development. Our comprehensive approach encompasses all aspects of the Supply Chain process, with our main focus being on ensuring optimal material cost, whilst retaining the flexibility to provide high level solutions. Cherrytech has a highly experienced purchasing team based in both the UK and Thailand who can procure materials from many approved suppliers worldwide offering competitive pricing and lead-time whilst in turn being flexible and cost effective. With our engineering team, we are able to cross the problematic, expensive, long lead-time components from your BOM’s with the available sources here in Asia, providing you with another solution for your product. In turn we can supply samples (Form / Fit / Function) for your test analysis and further evaluation of your product as part of the alternative component approval process.

Whether you have an established product or you are still in the development stages of your product journey, our dedicated business introduction team can offer advice on the lifecycle of your components. Using Silicon Expert, we can advise or completely take on the management of your bill of materials.

Sony takes these concerns seriously and is working closely with its suppliers on initiatives in fields such as human rights, labour conditions, health and safety, and environmental protection. These initiatives cover not only Sony’s own sites, but sites throughout the supply chain — from parts and material suppliers, to mineral mining operations, to production sites operated both by Sony and by subcontractors. Our Commitment to You: This focus to a sustainable supply chain will be applied to your products as well. We will recommend established trusted vendors, or work with you to ensure your preferred suppliers meet our compliance standards. Through our established Green Partner programme, we work with suppliers and support them to implement best practices.

With many years’ experience of purchasing from suppliers around the globe, you can be assured that we will always offer the most competitive pricing for the materials used within your products. We work very closely with our suppliers and always ensure materials are purchased from approved, traceable sources. Our relationships with these suppliers are often able to assist with cost reduction projects by using alternative materials where possible. If you would prefer to provide the materials ‘Free Issue’ or even part free issue, we are happy to accept these and will work with you to ensure the parts are fit for purpose with our equipment. We are happy to work with our customers to ensure you get the best service, we can accommodate various stocking arrangements such as: • Make to Order - Full materials and supply, Free Issue or Part Free Issue • Assemble to Order – For products where multiple variants are made using common materials and assemblies which are stored at our facilities. • Call-Off orders and Kanban • Scheduled Deliveries • Consignment Stock

We provide supply chain management, sourcing components through trusted suppliers to reduce risk and improve reliability. We are flexible and can support several material supply options depending on your preference – Full customer supplied (free-issue) materials Partial customer supply, where some components are free-issued and others are sourced by us Full turnkey supply, where we manage all component sourcing When customers supply materials or components we take care of them and treat them with the same care and attention as if they were our own. All materials are handled responsibly, stored appropriately and managed within our controlled manufacturing processes.

At Stewart Technology, our Surface Mount Technology (SMT) capabilities form the backbone of our high-quality electronics manufacturing services. With advanced Siplace placement lines, skilled technicians and strict process control, we deliver PCB assemblies that meet the highest standards of accuracy, consistency and reliability. SMT enables compact, high-density circuit designs, fast throughput and exceptional repeatability. Whatever your requirements, Stewart Technology provides dependable SMT assembly tailored to your needs. Each of our four SMT lines are fully standardised, giving us exceptional flexibility in production planning, rapid changeovers and the ability to adapt to customer needs quickly and efficiently.

Our Surface Mount Component assembly service allows us to respond to the growing need for more complex placement and alignment tolerances. Automated pick and place machines provide an excellent placement rate and fast configuration times easily accommodate the extensive product range and varying batch sizes required from our customers. Fully equipped manual re-work stations allow low volume prototyping work or product repair to be undertaken to the same high standards of our automated systems

Mycronic MY300DX 1 of 3 Pick and Place machines used in production.

Our process explained: We use high-speed automated pick and place machines, to place components with micron-level precision onto solder paste, with exceptional speed and precision. We have a long history of using Europlacer SMT placement machines which consistently achieve high quality results. Our current line up includes multiple Iineo II placement machines, which are widely configurable and feature major benefits such as high feeder count, large board size and wide component range. Because our SMT lines are identical, we have interchangeable feeders and programmes, giving us the major advantage of being able to offer greater flexibility and consistency, as well as offline set up. We also have integrated manufacturing with conveyer belts to reduce PCB handling. Our specification: SMT Placement Machines - Iineo II Places 30,000 components per hour, per machine PCB size: 500mm x 460mm – Can work with larger PCBs with engineering management Placement accuracy from ± 35µm to ± 60µm at 3 sigma, depending on the component type Min size components : 0.4mm x 0.2mm (01005 case) Max size components: 50 x 50mm Two heads with 8 & 12 customisable nozzles each Max PCB thickness: 10mm In line electrical test, whole feeder or part feeder testing
