High-quality, cost-effective contract electronic manufacturing and assembly

Precision microelectronics manufacturing

Microelectronics manufacturing from our state of the art facilities, Filtronic specialises in the manufacture of active and passive RF solutions for critical communications. Using highly automated processes, our manufacturing teams thrive on challenging projects where the solutions we produce push the boundaries of RF electronics and materials.

Producing precision components and hybrids to client specifications in our 24-hour production facilities, we offer contract design and microelectronic manufacturing services in both the UK and USA. Providing services that add value, make clients’ lives easier, and allow them to increase sales. We offer a range of order-fulfilment options, such as manufacturing close to market, inventory hubbing and site-kitting.

We also offer extensive volume experience to customise and adapt products, optimising them for cost-efficient volume manufacture. With our significant investment in hybrid assembly, advanced microwave test systems, military standard processes and full traceability, we offer a unique low risk and secure service.

Microelectronic manufacturing services (USA)

Filtronic offers competitive contract assembly and test services for a range of sectors including critical communications; telecom infrastructure and aerospace & defence from our Salisbury, Maryland site.

An overview of services include:

• Quick-turn electronics assembly
• Equipment build-up (including rack, stack and commissioning)
• Equipment and operational testing
• Repair depot with embedded process audit

Customised manufacturing solutions

Fully automated front end assembly including epoxy and solder dispense, die and component attach technology, wire bonding (ball, wedge and ribbon). Additional facilities include air cavity packaging and hermetic sealing.

All processes are supported by our in-house leading manufacturing engineers and process engineering teams.

Powered by people

We have a wide range of skill sets including:

• RF system engineers
• MMIC specialists
• Filter specialists
• Electronic and PCB layout designers
• Mechanical design
• Process engineers
• Software and firmware experts

Epoxy dispense and die attach

Fully automated epoxy dispense and component placement equipment provides tightly controlled, accurate and repeatable component attach.

• Deep access epoxy dispense capability
• Accuracy of 35um and repeatability of 15um

Die and component attach technology includes; Epoxy, Eutectic, Silver Sinter with an X/Y placement accuracy +/- 10 microns and the capability to pick from gel, waffle pack and reel.

Wire bonding

Filtronic’s fully automated wire bonding capabilities include wedge, ribbon and ball. Our team of highly trained and experienced wire bond operators ensure that all work is carried out to the highest standard. Robust & reliable wire bond process capabilities are developed by optimising and tightly controlling the key wire bond process and material parameters. Ball shear and wire pull test are used as tools to qualify and centre the process. Sample ball shear and pull test are then used during manufacture in order to maintain high levels of quality & yield

Air cavity package

Filtronic mixes GaAs, GaN and Silicon die in a single package offering unprecedented integration and system cost savings. To meet increasing demands for integration and cost reduction, Filtronic has developed a range of proprietary MMICs which are packaged in miniature surface mount multi chip modules enabling manufacture in mass SMT lines.

Supply chain resilience

Filtronic has a well-established global supply chain with strong supplier partnerships, and our buying power is increased by leveraging demand from multiple clients, which can result in significant BoM cost reduction. Our supplier partnerships include MMIC foundry and semiconductor vendors.

Screening

As part of the product design and microelectronic manufacture process Filtronic offer a comprehensive range of screening services. Filtronic has a range of in-house thermal HASS (Highly Accelerated Stress Screening) chambers which provide rapid temperature cycling of up to 60°C/Min ramp rate for screening out latent defects.

Dual sourcing

At Filtronic we have the capacity, experience and the expertise to design and manufacture high performance RF products at Microwave and mmWave. We are equally comfortable manufacturing to a customer’s design, as we are designing and manufacturing our own high-performance products. Alternatively, we love working with our clients, fusing their core competencies with ours to optimise their original design.
