HW & SW Development

Our Engineering team has extensive experience in the development of Hardware and Software solutions, allowing us to collaborate with our clients from the conception of the project where we define the design of the PCBA, selecting the most suitable components through specialized tools, carrying out the validation of the product and managing the project from its placement into series production to the management of its obsolescence.

Production Analysis

To avoid that a product may have a risk of being inefficient in time and production costs, at P4Q, we work with DFM (Design For Manufacturing) and DFT (Design for Testing) and we carry out feasibility studies aimed at defining the optimal process for its manufacture and testing, from product conception offering our customers the most competitive solutions to fit their needs.


It is essential to evaluate and verify the design as well as the correct performance of a product or project in the prototyping phase and our prototype manufacturing service is aimed at achieving the demanding manufacturing deadlines required in the development and validation phases of a product, reducing the Time-To-Market of our customers.

The manufacturing of prototypes is carried out with fully demonstrative means of mass production by our expert personnel.

To complement prototyping solutions we offer:

  • Vapor Phase Oven IBL
  • X-ray 3D validation
  • Climatic chamber and aging tests
  • Test by Flying Probes
  • DFM and DFT audits


P4Q provides different solutions in accordance to the needs of product verification, ranging from integrated AOI, 3D optical tests in all our SMD lines, electrical (ICT), to high level tests (Boundary Scan, JTAG), or X-Ray, through functional and hybrid testing.

The test strategies for the product are established in conjunction with our client, developing DFT (Design for Testing) that guarantees the optimization of both test investments and process times.

Our clients have direct access to test results, values and traceability of the units.


We have locations across the world in USA, Europe and Asia, situating our manufacturing plants strategically to provide market-focused services, cost-effective, high-technology manufacturing solutions that deliver innovation for our clients. Fulfilling the most strict quality standards, our global team of professionals work alongside our clients throughout the design and engineering process, whether we’re managing a turnkey project or filling a specific development necessity.

From reception and storage of materials in smart warehouses, to specific packaging depending on the characteristics of the product, we provide:

  • SMD lines prepared to assemble high complexity components.
  • Assembly of Through Hole components by Wave soldering and selective Wave
  • Conformal coating lines, in-line and off-line coating.
  • Electrical and functional tests equipment.
  • Burn-In cameras for product life tests.
  • Traceability systems at component level, with registration of each of the manufacturing steps and tests carried out.

Mechanical Assembly

We adjust our production capabilities to adapt to the needs of each client, that being an electronic assembly of a subset or a complete product assembly, which includes: assemblies of PCBA boards, plastic or metal components, motors and wire harness assemblies.

Product Upgrades & Obsolescense Management

We understand that effective obsolescence management is critical. In order to reduce the uncertainties arising from the volatility of the markets, maintain continuity and maximize profitability, we monitor, evaluate and control supply chain risk. We asses risks in process, control, supply & demand as well as environmental to identify possible disruptions in the supply chain and mitigate the possible effects making sure we implement the corresponding mechanisms of communicating and reporting.

The designs and maintenance of the electronic systems used in Railway are complex and are increasingly used to improve performance, communication and safety, as well as enhancing passengers experience.

In this respect, our electronic systems can be found in both onboard and infrastructure applications. Some examples are:

  • Chassis and sub-assemblies for traction system control.
  • Integrated frames for vehicle monitoring and control systems (lighting, doors, HVAC, etc.)
  • Communication and passenger information systems.


The industrial arena has been key to the creation and growth of P4Q. For almost 20 years we have worked with companies in the industry, offering services and customized solutions throughout the life cycle.

Relays, power meters and protection and control modules are some of the applications where P4Q electronics can be found.

We account for a reliable response capacity in operations and service along with a wide range of solutions; this enables P4Q to be a very important point of reference in electronic production.

We are industry leaders in production capacity, which together with the flexibility of our productive means enable us to deliver to our customer the high quality service that they demand, from low to high volume series.

Solar / Renewable Energy

In different forms at a technological level, and an indisputably effective way of contributing to Environmental Sustainability, is the use of on environmentally friendly energy such as wind or solar.

In this respect, P4Q works in both, with special relevance in photovoltaic and thermo solar technologies through our Suntrack solar tracking system.


P4Q provides solutions and Electronics Manufacturing Services (EMS) for the marine sector where electronics has experienced significant growth with many applications, providing technological solutions adapted to this industry.

We work together with our clients to develop and enhance our products according to their specific requirements in this industry, to be able to guarantee reliable, robust and high technological solutions.

Aeroespace y Defense

We account for state-of-the-art manufacturing facilities to manufacture highly complex electronic components for sectors with such high technical requirements such as Aerospace and Military.
