RFI shielding for modern manufacturing needs early design focus
Although EMC enclosures are not strictly electronic components, their design, manufacture and assembly onto the PCB needs to be considered at an early stage in the equipment design in order to avoid costly modification and delays in bringing the product to market. Offering a single-source solution to these issues, Tecan has a division dedicated to the provision of EMC enclosures which is set up to offer advice and assistance, from initial concept through to volume manufacture.

Although EMC enclosures are not strictly electronic components, their
design, manufacture and assembly onto the PCB needs to be considered at an
early stage in the equipment design in order to avoid costly modification
and delays in bringing the product to market. Offering a single-source
solution to these issues, Tecan has a division dedicated to the provision of
EMC enclosures which is set up to offer advice and assistance, from initial
concept through to volume manufacture.

Typical issues to consider include the shielding manufacturing process,
handling of the shielding during PCB assembly, packaging and the change to
non lead solder. Whatever the case, the company can deliver
application-specific solutions to meet individual needs.

The company's dedicated fast-response 'design to delivery' team offers
cost-effective bespoke screening solutions. Free consultation followed by
ongoing advice and support are available, saving time and costs from the
outset. The company welcomes entry into the system at any level, offering
value-engineered solutions whatever the individual case and ensuring
'defined costs for defined goals'.

Exploiting its detailed knowledge of RFI solutions, the company offers
structured levels of service, catering for those who know they need
screening but don't know where to go next, to those with fully dimensioned
drawings needing professional enhancements to incorporate special
manufacturing techniques, for example.

Typically, screening cans can be produced from an open-ended selection of
options such as fences, dividing walls, multi-cavity enclosures
(labyrinths), full enclosures, spring-finger lids, simple fold lids,
dimple-lock lids and screening meshes. Resultant fabrications are designed
to meet end-user's specific assembly and production requirements, such as
hand or machine placement, surface-mount or through-hole assembly, and
re-flow, hand and lead-free soldering issues.

Also offered are design guidance, site visits, prototyping, sample
production, finish and thickness options, forming, assembly and
re-evaluation of established designs for productivity enhancements and cost
reduction. The company uses a range of well-established and proven
manufacturing systems, such as photo-chemical machining (PCM) and punch /
press progression tooling, to provide cans for the most demanding low-,
medium- or high-volume production needs.
