DFMA for electronics manufacturing

DFMA – Design for Manufacturing and Assembly

What is DFMA for electronics manufacturers?

DFMA for electronics manufacturing is a systematic analysis of product design with regard to manufacturability and assembly feasibility.
This involves examining, amongst other things, printed circuit board layouts, drill holes, components, solder joints and assembly feasibility, in order to identify manufacturing problems at an early stage and to avoid additional costs and optimisation loops as far as possible.

The aim of DFMA is to

increase manufacturing efficiency
reduce sources of error
lower manufacturing costs
ensure timely market entry

Why use automated DFMA in the EMS industry?

Optimal time-to-market combined with reliable quality are more important than ever for electronics customers today.
The earlier a problem can be identified in the time-to-market process, the lower the additional costs and the less time is lost.

Manual layout checks are a time-consuming process during which important details can easily be overlooked.

Automated DFMA helps you provide the best possible support to your customers:

Quickly align customer requirements with your PCB manufacturer’s design guidelines
Early consultation with customers regarding manufacturing tolerances and risks
Early detection of layout errors to ensure on-time market launch

With automated DFMA, leave the data analysis to the algorithms and give your experts more time to discuss solutions with your customers.

The EMS business is a business built on trust and thrives on consultancy and early fault detection. That is why DFMA can help you strengthen your customers’ trust through early fault prevention.

DFMA – An Overview of Manufacturability

With automatic DFMA, you can see at a glance – in just a few minutes – whether there are any weaknesses in the customer’s layout and what form they take.

In a matter of moments, you can identify manufacturability risks or problems and provide your customers with targeted support in optimising their layouts, thereby saving them time and avoiding additional hardware costs.

DFMA – Pad classification

Automatic pad classification is used to assess the solder pads in terms of manufacturability and soldering quality. The pads are classified according to criteria such as size, shape, spacing and connection to copper areas, in order to identify potential problems such as inadequate solder joints, tombstoning or short circuits.

This enables critical pad geometries to be systematically identified and targeted optimisation recommendations to be provided to your customers to ensure a stable, reproducible soldering process.

DFMA – Clearances

Clearances and creepage distances are not always a matter of manufacturability – but in all cases they are a question of functionality and compliance.

By identifying clearances that are too small in the PCB layout at an early stage and reporting them back to your customers, you create added value that saves both development and testing time, as well as the costs associated with further hardware iterations.
