The effectiveness of board level EMI/RFI shielding depends on many factors: the design of the shielding can, material choice, thickness, venting, method of attachment and the ‘maximum linear dimension’ (the longest contiguous hole or slot). This maximum opening size is a function of the frequency spectrum of the device being shielded and of the attenuation you are trying to achieve.
Profiled and folded shielding cans offer many benefits, including bespoke design, exceptional co-planarity, low tooling costs etc., but one drawbacks is the corner seam, which can act as an emitter antenna if it is not folded and mounted with care. This corner seam can be soldered for complete integrity in high frequency applications but much of the time, the need is simply to reduce the maximum linear dimension.
A new finger joint arrangement on the corner seam allows two adjacent walls to interlock along the corner seam.

The Quiet Corner design reportedly improves noise attenuation and the mechanical stability of the shielding can.
Ultrasonic Systems will demonstrate the Optima Fluxing System at Productronica next month, in Hall A4 Booth 158. A new Ultra-Spray head produces a more vertical spray pattern, ensuring through-hole penetration when using water-based VOC-free fluxes.
Ultrasonically atomizes VOC-free flux into a fine mist, and then traverses the spray under the circuit at programmable speeds, ensuring flux penetration of the plated-through holes.
Can process circuit boards up to 24” (61 cm) wide and 0.250” (6.35 mm) thick, with plated through holes of 0.015” (0.381 mm) in diameter.

Micro-Line Digital Dispensing Head consists of a high-speed liquid metering valve and a precision nozzle.
Applies conformal coatings in precise lines or dots down to 1 mm with the liquid flow rate set electronically with the Prism software. The coating is applied at a distance from 5 to 15 mm between the nozzle tip and the substrate. The technology is said to be more effective than conventional needle dispensing.
