New low-profile PCB screening cans and enclosures

Tecan : 23 June, 2006  (New Product)
Low-profile PCB screening cans and enclosures, which can be re-flowed with conventional and SMD components, are now available from Tecan.
Standard-pitch screening cans, delivering solutions for prototype, development and production needs, are available as single components. The wide range of low-profile and surface-mount components offers a fast and effective means of sourcing radio frequency interference screening, at optimum cost. The range encompasses a selection of can sizes, profiles and mounting options, allowing users to select components, which assure both maximum RFI performance and compatibility with individual production requirements. Based on standard component pitches, the cans can be supplied with a wide choice of lids, sidewalls, and mountings.

The company produces PCB cans and fences, from simple regular box designs to complex enclosures with profiles to suit individual applications. Options include reflow Plimsoll line, which minimises the vertical migration of solder during the reflow process, thereby increasing solder fillets and reducing voids and blow holes. Maintaining tight co-planarity constraints demanded by high-volume manufacturer, post reflow electro-mechanical integrity and aesthetics are enhanced, quality control pass rates and yields are raised.

Eight standard configurations include, a 4-sided can with a spring fingered lid, a 4-sided surface-mount fence with a spring-fingered lid, a 4-sided can with a tag-and-slot lid, a 5-sided can formed and spot welded, a 5-sided can formed for surface mount, a 5-sided can supplied flat for self-forming, a total enclosure with a spring-fingered lid, and a 4-sided fence with 2 spring-fingered lids. The standard pitch system utilised covers 20mm x 20mm to 75mm x 125mm. Low-profile cans are available down to 2.5mm high.

The company uses a range of well-established and proven manufacturing techniques, 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.
