Perancea Ltd

Peranceas enhanced range of eight and 11 pin plug-incases are completely retooled designs and feature product lines revised to meet the current increasing market demand for ex-stock, low cost, high reliability cases. The improved design provides environmental protectionfor packaging small assemblies in traditional style applications including timers, machine tool cycling, light controllers and control panels in the electronics and electrical industry sectors. The new cases also provide easy plug-in replacements that are fully interchangeable with existing sytem designs from alternative manufactures. The 50mm square plug-in cases are available in cover heights of 41 an d76mm. The high impact resistant polycarbonate covers can also be supplied in a wide range of colours for volume applications. The interchangeable case tops simply snap fit on to the pinned bases which are moulded in low friction glass filled nylon.

Have an integral mounting device, allowing cable looms to be secured to panels, chassis etc. A secure snap fit ensures a strong and lasting fixing.

Incorporate an integral fixing hole moulded in the head of the tie, giving a very economical method of securing.

As with most simple concepts, practical EMC shielding requires considerable engineering skill to give good results. However at product enclosure level, it can be complex and expensive, adding to both material and assembly cost. Added to that affective enclosure shielding usually requires substantial filtering of all cables which pass out of the product, right at the point where they penetrate the enclosure shield. Tackling an EMC solution cost effectively and conclusively, shielding at PCB level is simple and low cost. Board level shielding solutions can be used to achieve an EMC performance that would be far more difficult and costly at product enclosure level. At board level, small shielding cans can be applied selectively to the problem areas of a circuit, directly tackling componets with emissions that are too high ir too sensitive. In effect, PCB shielding cans are simple metal boxes taht are easily soldered in pace,much like any othe board level component. Tackling EMC problems at this level, keeps component and assembly low and appearance and ease of maintenance of the product are not compromised.

Perancea has developed an effective yet low cost solution for the preventionof solder creepage up the sides of its PCB moutning screening enclosures during automated and reflow soldering processes. If solder migration is an important consideration in your application, Perancea can provide a solder/tin free barrier that will prevent solder wicking up the side of the can or frame.The barrier essentially provides a physical break in the plating so that solder will only flow to the height of the line and not beyond it thus ensuring good quality solder joints. The linear barrier is set around the circumference of the enclosure at the optimum height from the PCB to suit individual applications. It is normally 0.15mm wide with a depth commensurate with the surface finish.

An Ideal solution fir the segregating of sensitive components or circuitry to eliminate or minimise the interference between different parts or the circuit.Range of heights, adaptable, Custom Fit, Labyrinths, Custom sizes and Altenative Materials.

Perancea has developed its expertise for fabriaction using thin gauge materials down to 0.2mm based on extensive CNC technology providing a high competitive alternative solution to chemical etching. Based on the significant advantages of the companys ready formed boxes and enclosures. Perancea solutions are shipped and ready for instant use rather than a flat sheet forms taht require folding as normally assosiated with chemically etched parts.

Where tooling cost is a major consideration in plastic applications, vacuum forming is highly viable alternative to injection moulding, dramatically reducing tooling outlay by a factor of 10 or more.

Vacuum Forming, also know as thermoforming , enables complex plastic shapes to be cost-effectively and accuratley produced. It is ideal for a whole host of housing solutions such as boxes and enclosures or intricate detail within custom made component handling trays for example. The stages of the process are illustrated left. In operation, a plastic sheet is clamped in the vacumm forming press and pre-heated. A short blast of air is then directed underneath the sheet before it is subsequently drawn down under vacuum on to the mould. The simplicity of vacuum forming has major advantages including significantly lower cost tooling compared to injection moulding notably, complex shapes do not necessarily mean a more expensive and product. Vacuum forming is ideal for prototypes and inexspensively tooled prototypes can usually be produced within a few days, enabling your design team to quickly and efficiently evaluate the component and test materials. Any alterations or modifications are easily accomodated, ensuring the design is perfectly suited to your needs before comitting to final production tooling. The moulding process is extremely flexible and enables intricate features to be easily integrated that other wise would be difficult and thus expensive by alternative fabrication methods. once tooled, these features can be reproduced accuratley time after time after time. If you have a component that is cost sensitive and could be vacuum formed, call Perancea now. Wemay be able to break down the traditional mould.
