New Product Introduction (NPI)

Minimise your Time to Market and Reduce Production Costs

Our New Product Introduction (NPI) service provides fast turnaround, high quality prototypes and far more.

We have dedicated staff who work with your designers to ensure optimum design for manufacture and test. We provide feedback during the product development stage to identify cost savings both for product launch and on-going volume production.

We regard ourselves as an extension of your design team and an essential part of our service is to document for you the agreed improvements and observations made regarding your products. This forms part of the continuing dialogue with you for continuous improvement.

Design for Assembly for Economy and Convenience

Cost-effective PCB design depends on our ability to combine our customers’ requirements with an in-depth knowledge of the manufacturing process. Using modern design aids, we progress quickly and precisely through each stage of the design process, working with you in close consultation to gain a thorough understanding of your needs. Qualified in Altium Designer and Mentor Graphics, our in-house team has the vision and experience to take your design concept and develop it into a tangible product, on time and on budget.

Our Design team can also assist in the following areas:

• Design for Assembly (DFA) is a continuous process in which assembly, fabrication and layout must all work together. The layout designer plays an important role in this, acting as an intermediary between the engineer, board fabrication and assembly needs.

• Good DFA practice also requires the component placement to allow for the effortless replacement of a faulty component if required

• We can also re-engineer intelligent CAD data from existing flat Gerber data.

• Flexi and flexi-rigid Design • Packaging Design

• Enclosure and rack Design

• Chemigraphic offer the full service from initial

development, in house design, prototype, testing and the subsequent production of any associated hardware. • Library and design work all carried out using relevant IPC standards:

- IPC-7351, IPC-2221A, IPC-2152 • Altium 3D output for fast and accurate mechanical checking

Benefit from our Expertise, Systems and Purchasing Power

Chemigraphic has a dedicated purchasing department with a highly experienced team of qualified buyers.

Our global supply chain gives us the ability to source specified parts on behalf our customers and ensure that they arrive on time and are fully inspected and stored in the appropriate manner.

Chemigraphic procures upwards of 1.5 million components a month – comprising PCBs, passives, semiconductors, connectors, cables, metalwork, plastics, fixings and much more.

Within our approved supplier base we have a global sourcing platform covering both active and obsolete components - if it is available then we will find it! Working closely with our supply chain, we have up-to-date knowledge on the availability of all our currently used materials and can advise our customers on any potential supply problems.

Security of Supply

When a customer’s product is on-going we will arrange for long lead time or difficult to obtain components to be buffered, ensuring continuation of supply.

Where components are becoming obsolete, in consultation with our customer, we will arrange for last-time buys of sufficient stock to cover production to a product’s end of life. Following the introduction of RoHS compliancy, many components are no longer available, due either to the rationalisation of component manufacturers’ production lines, or having had their part numbers changed. To assist our customers - many of whom are exempt but have

Business Continuity – Your Reassurance

Chemigraphic operates a Business Continuity Policy to the requirements of BS 25999-2-2007.

We expect our suppliers to be aware of this and cooperate fully in achieving its objectives. The full policy statement is available upon request, but briefly states:

The scope of Chemigraphic’s business continuity policy relates to the continuity management of its design, development, manufacture and test of prototype and production, electro-mechanical and electronic assemblies, sub-assemblies and complex cable looms.

Its objectives are to ensure the prompt and efficient recovery of these essential operations, from any incident or disaster occurring at, or to, the company. We are therefore committed to developing, implementing, maintaining and continually improving a Business Continuity Management System (BCMS) with the primary objective of preventing or restricting disruption to a level that does not impact adversely upon our stakeholders.
