Can-on-board solder migration problems solved
Tecan Components has solved a range of problems associated with automated soldering of RFI screening cans/fences onto PCBs with the introduction of the 'Plimsoll line and lattice bridging stencils'.
Labyrinth RFI screening can brings RFI benefits
A labyrinth RFI screening can is an effective one-part board-level alternative for PCB designs which would otherwise require solid metal enclosures or multiple screening cans.
In addition to higher resolution bars and slots, the accuracy of the drive shaft hole is significantly improved.
The company offers a bespoke service for the supply of burr- and stress-free disks and similar components - including simple or complex designs for low-, medium- or high-volume requirements.
Different manufacturing techniques are employed by Tecan to produce the right encoder for a given requirement.
Photochemical machining, for example, will produce excellent results for a wide range of applications, typically with accuracies of +/-10% the thickness of the metal used - from 1.5mm down to 0.01mm.
In cases requiring even greater accuracy, electroforming manufacturing techniques are utilised, a typical tolerance here being +/-8um, in some cases ultra high-tolerances of +/-2um can be achieved.
Single-thickness or bilevel disks can be produced readily.
Very cost-effective and speedy production are assured because tooling costs are low and turnround is fast.
The techniques, especially electroforming, are ideal alternatives to expensive sputtered-glass encoder manufacturing, says the company.
Subject to acceptance, a bespoke rapid prototype service guarantees despatch of first samples within five working days.
In addition to rapid delivery of the first low-volume parts, the service has other benefits.
For example, once a part is adopted, down-the-line production speeds and costs are reduced because the tooling is already in place.
Modifications can be cost-effectively incorporated within the company's powerful CAD system, ensuring any knock-on tooling costs are also minimised.
