Development and testing of prototypes Prototyping

development step 4

Prototypes are produced to check the development concept, the electronic circuit and the printed circuit board layout that have been created. Therefore prototyping is another important step. For this purpose, pironex creates prototypes or more precisely sample assemblies, in the quickest time possible. The A-samples are manufactured as individual copies with manual assembly. In this way, functional device models are built for software development and housing construction in the shortest possible time. With these samples, the basic function of the developed module is developed and tested.

Assembly service providers are already involved in the production of the B samples. For this purpose, pironex relies on proven suppliers. These EMS service providers build a small number of assemblies for functional software development and field testing.

Prototype Construction

Making Developments Tangible

At pironex, the sample assemblies are produced quickly and cost-effectively. The assembly of the industrially manufactured printed circuit boards is done manually, which is not only fast but also guarantees accuracy. The assemblies are then soldered in a vapor phase soldering oven and thoroughly tested.

The biggest advantage of the manual assembly is the speed, i.e. the reduction of the project duration. The time-consuming and lengthy request from the assembly service provider is no longer necessary. Pironex acts immediately and can reduce the times for the development loops.

 

Assembly in Prototype Construction

The SMD and THT assembly of prototypes is done either manually or automatically. Devices for paste printing, reflow and vapor phase soldering are in use at pironex.  The optical inspection of the assemblies is carried out with modern microscope workstations.  For smooth production, the purchasing and production departments acquire the active and passive components from a wide variety of distributions and catalogue suppliers.  Thanks to our flexible workflows and processes, we can produce sample circuit boards and assemblies, as well as equip them with THT within just a few days.

Flexible Cable Assembly

Regardless of whether standard or customised enclosures are used, all connectors and terminals of the assembly have to be adapted.
In perfect interaction between 3D design with Solid Works and the PCB programme Altium Designer, the design of the PCB shape, connectors and the pin assignment for the connectors is carried out.
Customised enclosures are optimised in terms of production costs and manufacturability. If required, the mechanical design can be carried out for the integration of the electronic assemblies in any installation environment. We work primarily with the 3D CAD system Solid-Works.

Test Equipment and Test Devices

Pironex develops and builds devices and software for functional testing and the EOL test at the producer. The range of functions of the test equipment increases with the complexity of the developed device.

Test development includes a wide variety of test processes:

  • Programming of the assembly controllers
  • Parameterization of the system components
  • Assembly test with needle adapter
  • Interface test with external test adapter
  • Testing of the radio interfaces
  • Boundary-scan Test
