MPE Electronics

Pre-Manufacture

MPE Electronics offers a full prototyping service for Printed Circuit Board assemblies and can provide all the information you need on component pricing, availability and obsolescence. We work closely with our customers to advise and guide them on PCB layout for manufacturing and testing before releasing boards for production.

Component Procurement

A fully computerised stock management system means that ordering and updating of materials is kept under close control. Meanwhile, access to major worldwide distribution outlets means we can source just about any component needed to produce your customised PCBs. 

Find out more about component procurement at MPE Electronics by heading over to our website or calling us on 01825 764822.

Surface Mount Assembly

Our policy of continuous reinvestment has endowed us with a range of surface mount technologies that enable the fulfillment of even the most complex PCB orders. Our automatic placement equipment allows us to place BGA, FPGA, Micro BGA and discreet components to 0201 size. The manufacturing process includes automatic paste printing using DEK printer technology and lead-free soldering using BTU convection reflow systems. Find out more about our surface mount assembly services by visiting MPE Electronics online.

Through Hole Assembly

Depending on the batch size and board complexity, leaded components are pre-formed, manually inserted and either wave or hand soldered. All operators are trained to IPC610 workmanship standards, ensuring component quality, performance and reliability. For more information on our through-hole PCB assembly services, visit MPE Electronics online or get in touch on 01825 764822.

Inspection

To ensure that our components meet the standard required, we use a Mirtec Automatic Optical Inspection (AOI) system. Utilising state-of-the-art software, this machine has true character recognition and by a variety of lighting techniques is able to identify most solder defects. The Mirtec Automatic Optical Inspection system is programmed offline so that it does not interfere with daily production requirements. 

BGAs and micro BGAs, meanwhile, are inspected using an Ersa Scope Optical System. 

For manual inspection we use Mantis 2x – 10x viewers as well as an EV microscope with 10x – 50x magnification.  

Test

Most of our customers require a fully tested board assembly. To meet this requirement we have a dedicated test department where Automatic Tests (ATE), comprehensive in-circuit tests using TRI Manufacturing Defect Analysis Systems (MDA) and semi-automatic jig tests are carried out. Environmental tests can also be performed using our Montford environmental chamber, which has a temperature range of -40°C to +125°C.  For more information on our PCB testing services, please visit MPE Electronics online.
