Our electronics engineers are trained to IPC 610 standards, assuring a quality finish and 100% customer satisfaction.

We have also established a reputation in leading edge technologies, providing customers with improved levels of miniaturisation. CIL currently possesses the largest independent chip and wire bonding facility in the UK! All of our processes are undertaken in line with ISO 9001 quality control standards.

CIL doesn't just manufacture your electronics – we also offer a comprehensive design service, providing a complete circuit and product design facility which employs CAD software for Printed Circuit Board and Advanced Substrate Circuit design. Our wealth of experience and breadth of expertise is at the disposal of our clients, helping them to create electronic circuitry in the most practical and cost-effective way.

After helping you to design your electronic assemblies, we can also offer a rapid prototype and early model production service. Our highly flexible production lines are quickly and easily configured to meet the production needs of your design. Indeed, in some cases we have even completed same day production! 

So for an all encompassing electronics design, prototyping and manufacturing service, Custom Interconnect Ltd is your premium choice of partner. Give us a call today for an initial discussion of your requirements.

SMT Board Assembly

CIL's manufacturing group offers a comprehensive electronics assembly service. We have an area dedicated to SMT assembly, offering a great combination of flexibility and technical capability. The Surface Mount Assembly area regularly carries out the placement of 0201, BGA, and even Bare Die
components, while the use of leaded, unleaded and HMP specialised solders is commonplace. We have four fully automatic SMT assembly lines, allowing CIL to accommodate for small to large (hundreds, thousands) production volumes. To find out about the technology we use on these lines, pleasefollow the link to the SMT Board Assembly page on the CIL website.

Electronics Product Build

CIL offers a full product build service which includes the assembly of the electronics and PCBs into the final product. This can be anything from a small desktop instrument or hand held device, to more complex assemblies employing mechanical frames, turned parts and mouldings. Flowline production facilities and In-Line testing equipment enables us to cater for high volumes or lower volume specialised builds. We also offer to test and configure the final product ready to be used in our customers' own production areas, or to be shipped directly to the end user.

Fast Track Purchasing

CIL has built a fast track purchasing team that are quickly able to determine the critical tasks and procurement needs of any given project. This fast track purchasing activity can be incorporated into the main MRP system or excluded and micro-managed by CIL. Our customers are provided with data
and samples and are assisted by the CIL Supply Chain in order to ensure they retain the technical support available from component manufacturers. We also provide estimates and commercial proposals for new projects.

Production Lead-times

Between 3 and 5 days are usually allotted for the production and manufacturing cycles of a new project. However, additional tests (such as flying probe testing) of early models may result in longer time-frames, depending on the complexity and coverage of the assemblies involved. We posses our own X-Ray and 3D measuring equipment, meaning we do not need to sub-contract the project. This tends to result in shorter lead times.

Die Bonding

We use both epoxies and eutectic solders to complete conductive and non-conductive die bonding. Our facilities currently include two fully automatic die bonders capable of large throughputs, as well as one manual die bonder for tight tolerance die placement. These are used for a variety of semi-conductor die types, including LEDs, ASICs, MEMs and Sensors that are typically used in medical, industrial and commercial devices. We have the capability to die bond to a range of substrates, including Alumina, Metallised Ceramic, Carbon Fibre, FR4 and Chip on Flex. CIL is particularly experienced in bonding Opto-electronic dies.

Wire Bonding

We use wedge bonding and ball bonding processes to bond aluminium and gold wiring. Over the past few years, CIL has invested heavily in this area and has acquired two fully automatic aluminium wedge bonders and one automatic gold ball bonder, as well as an additional manual heavy gauge aluminium wire bonder. These state-of-the-art machines, coupled with our high precision die bonders, mean CIL offers a bonding capability that is unrivalled anywhere in the UK.

Hardware Design

We offer a full design solution that includes circuit design using PADS PCB CAD including SPICE simulations, PCB layout using CAD, Design for Test, Project management, global component sourcing, product certification and qualification (such as CE marking), and lead free compliance. To find out more about our hardware design service, please visit our website or simply give us a call!

LED and Opto-Electronics

Following an intensive research programme with the Optoelectronics Research Centre at Southampton University, CIL has established itself as one of the world’s market leaders in custom LED displays. Our ergonomic designs are produced in a high package density, making them suitable for many industrial applications. After five years of R&D in the field, CIL has gone on to become a Future Lighting Solutions Integration Member for Phillips' LUMILEDs. To find out more about our expertise in LED and Opto-electronics, simply follow this link to the Custom Interconnect website.

LED and Opto-Electronics

At CIL, we specialise in outstanding LED and Opto-Electronics services. In fact, we are market leaders in the design and manufacture of custom LED arrays.

Each year, LED performance increases dramatically with higher output covering a broader range of wavelengths. However, despite vast improvements in performance and the increased use of LED’s as a replacement for incandescent lamps, designers are faced with problems such as the balance of basic physics of increasing light output while dealing with the heat that is generated.

At CIL, we have the skills and experience to overcome such problems as this and have been working in this field for the last five years. We have become a Future Lighting Solutions Integration Member for Phillip’s LUMILED’s.

Customer Supplied Materials

We are pleased to accept materials from customers during the early stages of production and prototype build. All customer supplied materials are checked and discrepancy issues reported prior to use. They are used or issued on a regular basis and coded as Customer Furnished within our material control system for easy identification.

New Product Reporting

At CIL Engineering, we now formulate and collect data that has been measured and observed during the prototype and early model production phases. This data is available to customers along with recommendations and corrections required to improve any follow-on production processes.

New Product Introduction reporting helps customers identify any product improvements as early as possible in the product life cycle.


We have been designing and manufacturing products using bare die and packaged CREE LEDs since 2004. Our manufacturing equipment is set up to handle CREE bare die and CREE packaged LED’s and mount them on to various substrates such as FR4, metal clad PCB’s, ceramic and more.
