Why Choose Newbury Electronics For Your PCB Assembly?

Modern electronic assemblies are complex beasts. It is no longer possible to sit down with a fine tipped soldering iron and start assembly. The size and fine pitch of electronic components render hand placement impractical. At PCB Train we have developed an electronic assembly process that uses the very best technology available and applies it exclusively to small and medium batch manufacturing. We are one of only a small number of specialists in this field.

What is our PCB Assembly service?

With 60 years of experience, we’re experts at high volume PCB assembly quotes, ranging from a single piece up to 10,000 and beyond. We’ve consistently delivered high-quality products to many different customers, no matter their request. We use both surface mount and through hole technology in our PCB assembly process and our production environment thrives using highly demanding SMD technologies, including box-builds.

The technical capability does not end there as we’re able to work with hand assembly of through-hole components as well as automated placement of micro-BGA parts. Our components are of the very highest quality, and our inventories are managed so that we can service any electronic assembly request. Our delivery times are as fast as possible, just 3 working days from the receipt of your order. We offer an online PCB assembly quote service for your convenience.

Who uses our PCBA service?

Our client list consists of those who value an agile and dynamic PCB assembly manufacturer. We’re responsive to the demanding needs of a competitive electronic market.

It is ever-changing, and so are we. Such clients may be universities, development laboratories, professional electronic equipment manufacturers, racing car manufacturers, and more. In fact, we’re able to cater to anyone who needs electronics, and we’re always excited to take on a new type of client.

Every single product, whether its production run is a simple 1 piece or a huge 1,000,000 pieces, progresses through our development and pre-production phases in impressively short lead times; something we are proud of.


PCB fabrication is the manufacture of a bare PCB board. PCB assembly is the process of mounting and soldering components onto a bare PCB board.

Through-hole components are inserted with their legs passing through the holes in the PCB.The component legs may have to be pre-bent and cut first. The height of the leaded component above the surface of the PCB may have to be adjusted because not all components sit flush.The legs of the component are soldered either by hand, by selective soldering machine, or by wave soldering. Depending on the soldering process, component legs will be cropped either before or after.

Surface mounted devices (SMD) are machine-placed flat onto pre-solder pasted pads. The solder paste is reflowed either by infra-red, convection, or a vapour phase reflow oven. SMD components may be hand soldered with a soldering iron, but this is a laborious and low-quality method. Components with pads underneath the body of the device cannot be soldered by hand.

Leaded parts, which are now favoured less and less, are often placed by hand because the machines built to place leaded parts are long since obsolete. SMD parts are usually placed by pick and place machines, many of which can place 10s of thousands of parts per hour. SMD components may be placed by hand if the quantities are very small.

Solder paste, which has the consistency of butter, is screen printed onto the component pads on the surface of a PCB.

The top three are:

1/ Each bare PCB must be perfect. Any damage or defect will render the assembly unusable. It is standard for every bare PCB to be electrically tested first.
2/ Ensuring each and every component pad has the correct amount of solder paste for a quality joint.
3/ Ensuring each component is of the correct value, in the correct place, and in the correct orientation.

A typical run of 50 PCBs with 100 components on each may only be running on the pick-and-place machine for around 1 hour to place and reflow all the components. However,this all depends on part availability and it may take a week to receive all the parts after placing orders with suppliers. Checking and kitting in parts, programming the SMD machine, cutting the solder paste screen, and fitting the component reels onto the trolleys which fit the SMD placement machines will add more days to the process. Before a batch of assemblies is run on the SMD machines, a first-off is produced and thoroughly checked. Any error would be reproduced 50 times over.

You will need PCB design data in Gerber format and a bill of materials (BOM). We can quote and build the assembly from this data.

Newbury Electronics has 65 years of experience designing PCBs, fabricating bare PCBs, and assembling PCBs. We are the longest-established continuously trading PCB fabricator and assembly company in the UK and dedicate our efforts to manufacturing the best bare PCBs and electronic assemblies possible. We use up-to-date digital technologies at all stages of manufacture and are ISO9001 and AS9100 approved. If this wasn’t enough, a full online quote and order website is always available to all our clients.
