Getting Outside the Box (or in this case ‘in the box’) Installment #2 in the ETI Always Made Custom – Design Innovation Series

Wednesday, August 3rd, 2011

Electronics are getting smaller, often reduced to single board computers.  We need to have a packaging solution which protects the electronics, provides the ability to mount the product, and facilitates power/data transfer. For larger solutions – this generally means some type of chassis or system.  But for smaller configurations,  an enclosure such as the options shown below, are often required.

To reduce cost,  while providing a robust and stable mechanical mounting solution – features such as those listed below are generally integrated into the solution :

  1. Wall or pole mounting options
  2. Board slots
  3. Conductive/EMI provisions as needed
  4. Provisions for IP or EMI Gasketing
  5. Front/Rear Endplates for connectors and I/O
  6. Labeling

So how do you get from your single (or multiple board solution) to the right enclosure design….

Matt Travers – our roaming applications engineer provided the following guidelines:

First – start by identifying the key features which are critical to your application

  1. IO
  2. Power/Thermal
  3. Mounting requirements
  4. EMI Specifications

Next – look for an enclosure solution which most closely meets your requirements.  Generally for low  to medium volume- but robust application equirements  – an aluminum enclosure is the answer.  These can be customized for low runs starting at 100 units, with tooling costs of less than $1500.  For high volumes later in the project’s life cycle – the transition is often made to die cast.

For details on a whole range of standard off-the-shelf enclosure options – visit our Aluminum Enclosures page.

Now – armed with your PCB layout, such as shown below, we can work with your engineering team to design an enclosure customized to meet your  application.

Using a standard configuration as a guideline, such as the WS-4517 below, we will work to adapt the design to your application requirements.

From this standard solution – we were able to configure a solution which  accommodated the custom board layout, all of the IO requirements,  and was also adapted to meet the customer’s aesthetic requirements.

With the right design engineering partner,  and a standard enclosure solution to guide the way – a cost effective,  fast time to market solution – is readily available….

Rugged Aluminum Enclosures – For GPS to Cameras to Instrumentation

Rugged aluminum enclosure solutions

With the growing demand for remote monitoring, tracking, and process control – cost effective, robust enclosures solutions are needed to house the electronics.  Factors to consider in selecting an enclosure include:

● Environment (sealing required, waterproofing, vibration)

● Mounting

● EMI Shielding Effectiveness needed

● Volume

For many applications – an aluminum enclosure – is often the perfect solution. Aluminum provides a lightweight and rugged package.  In addition – it can be either extruded or die cast.   Low to medium volume situations – an extruded solution is typically more cost effective.  Not only tooling costs are significantly lower – but the minimum lot sizes can be very low.  Extrusions also provide a level of flexibility when it comes to embedding features such as flanges for mounting, pcb mounting/guides, or connector mounting – into the enclosure. These save money from both a material and labor cost.

For high volume – where the tooling is justified to reduce the piece part price – the aluminum enclosures can be converted to die cast from extrusions.  Die casting often offers additional flexibility in terms of shape and embedding features.

Some examples of the types of applications where robust enclosures are key include:

● GPS and tracking devices on vehicles (from buses to trucks to military vehicles)

● Process control instrumentation

● Communication devices for sensors

● Industrial camera

● Repeaters
