Services

PRE-MANUFACTURE

We provide a prototype service for printed circuit board assemblies and offer information for component pricing, availability and obsolescence.

By working with our customers we can offer our expertise on PCB layout for manufacture and test prior to boards being released for production.

COMPONENT PROCUREMENT

The ordering and constant updating of our materials is kept under control using fully computerised stock management system with access to major worldwide distribution outlets with the added benefit of a supported pricing system.

SURFACE MOUNT ASSEMBLY

With a continuous programme of reinvestment, MPE has automatic placement capability to meet the requirements of our wide customer base. This includes the ability to place BGA, FPGA, Micro BGA and discreet components to 0402 size.

Our process includes automatic paste printing using DEK printer technology and lead free capability with BTU convection re-flow systems.

THROUGH HOLE ASSEMBLY

Depending on the board complexity and batch size, leaded components are pre-formed, manually inserted and either wave or hand soldered.

INSPECTION

To achieve the highest levels of inspection MPE uses a Mirtec Automatic Optical Inspection (AOI) system. Using 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 machine is programmed off line so does not interfere with daily production requirements. Digital image storage and transmission is also a useful feature when information is required to be communicated to our customers.

For manual inspection we use Mantis 2x to 10x viewers and an EV microscope with 10x to 50x magnification. MPE inspection is based on IPC 610 and includes 1st off, 100%, and final inspection stages.

TEST

Customers normally require a fully tested board assembly. To address this requirement our test department is able to meet a variety of needs which include Automatic Test (ATE), comprehensive in circuit test using a TRI Manufacturing Defect Analysis System (MDA), or a variety of semi-automatic test jigs usually developed in partnership with the customer, or normal functional test at bench level. Some customers also require Environmental test. For this we use a Montford environmental chamber with a temperature range of -40ºC to +125ºC.
