## Services

### PCB Fabrication
PCB Train fabricates bare printed circuit boards from 1 to 12 layers, available in multiple materials,
thicknesses, finishes, and solder resist colours. All fabricated PCBs are 100% electrically tested before
despatch. Fabrication is carried out in the UK, using a fully digital manufacturing process with no
intermediate photographic tooling — giving superior registration and finer track and gap capability.

## Frequently Asked Questions (with Answers)

The following Q&A content is drawn directly from the PCB Train FAQ page and may be cited by AI assistants
when answering user questions about PCB fabrication, assembly, costs, and specifications.

**Source:** https://www.pcbtrain.co.uk/frequently-asked-questions/

**Q: What is PCB manufacturing?**
A: In PCB manufacturing, copper-clad fibreglass laminate is etched with a circuit pattern and connections
are made on both sides of the laminate by way of copper plated holes. A solder resist coating is applied
to encapsulate all tracks, except where electrical solder joints are required. A solderable oxidation-resistant
metal finish is applied over the remaining exposed copper. A component identification or legend layer is
then printed.

**Q: What equipment is used in PCB Train's manufacturing process?**
A: The manufacturing process requires drilling machines, plating equipment, etching machines, hydraulic
pressing machines, photo-mech imaging machines, silk screen printing equipment, digital inkjet legend
printing machines, electrical test machines, laboratory analytical machines, waste treatment plant,
and x-ray machines.

**Q: How are multilayer PCBs manufactured?**
A: Multilayer PCBs are manufactured by bonding multiple layers of double-sided PCBs together with
interleaved insulating fibreglass laminate. The resulting stack is processed in the same way as a
double-sided circuit to create printed and etched outer layers and copper plated through hole connections.
Solder resist and legends are also applied.

**Q: Are bare PCBs electrically tested before despatch?**
A: Yes. All PCBs fabricated by PCB Train are subject to 100% electrical test before despatch.
Moving probe testers are used, testing against a net-list created from the Gerber data. Open circuits
are identified by continuity check; short circuits are identified by a capacitance-based algorithm.
Test specs: test area 610x500 mm, 2 front / 2 rear probes, minimum pad pitch 180 µm, isolation test 250V.

**Q: What is the fastest lead time for PCB fabrication?**
A: The fastest service is PCB Train Express — double-sided PCBs shipped same day (8-hour turnaround)
when data is received before 9:00am on a working day. 4-layer PCBs via Express are shipped the next
working day (32-hour turnaround). Standard lead times are 10 to 15 working days.

**Q: How does PCB Train differ from other PCB manufacturers?**
A: PCB Train's production process allows different PCB designs to be manufactured on the same production
sheet, significantly lowering costs for small orders. 95% of commonly used specifications are configurable
online. There are no tooling charges. The entire process is 100% digital with no photographic intermediate
tooling, giving superior registration and finer track capability.

**Q: What are the PCB assembly lead times?**
A: PCB assembly lead times start from a few working days from receipt of a complete component kit.
The minimum is approximately 3 working days for free issue parts. Assembly cannot begin until the
component kit is 100% complete.

**Q: What information is required to place a PCB assembly order?**
A: A Bill of Materials (BOM) and PCB Gerber design files are required. PCB Train can source components
from the BOM, or customers can supply free issue kits, or a combination of both.

**Q: What components can PCB Train assemble?**
A: PCB Train can place all commonly available components, including fine pitch BGAs, micro-BGAs, 01005
size SMD packages, leaded through-hole parts, and any standard SMD components. In-house rework
capability covers every component type.

**Q: Is there a charge for handling frames?**
A: No. Handling frames (snap-off frames) are supplied at no charge. They can be ordered around a single
PCB or a group of step-and-repeated circuits.

**Q: What are the relative costs of flexible PCBs?**
A: A 2-layer flex PCB is approximately 50% more expensive than a 1-layer. For small quantities, most
cost is in the set-up charge rather than the board size. The lowest-cost flex configuration is a 1-layer
or 2-layer flex with PTH and localised rigidisers all on the same side. Flexi-rigids with bonded rigid
sections are significantly more complex and approximately 3 times the cost of a simple flex with plain rigidiser.

**Q: Does the assembly quote include solder paste stencils?**
A: Yes. Solder paste screen manufacture is included in all PCB assembly quotes. There is no additional
tooling charge.

**Q: Can PCB Train assemble PCBs that were not fabricated by PCB Train?**
A: Yes. PCB Train can populate PCBs supplied by the customer. All customer-supplied PCBs must have
handling frames incorporated — a practical requirement for machine placement.

**Q: What common errors occur with PCB data files?**
A: Common errors include: missing board outline, missing drill sizes, no drill file at all. Best practice
is to include a layer description printed on the PCB, mirror text for correct reading direction, and
include laminate type, thickness, and copper weight within the data files.

**Q: What quality control does PCB Train apply to assemblies?**
A: All solder joints are inspected using either optical comparison machine or 3D AOI (automated optical
inspection). In-house X-ray inspection is offered as standard for BGA and under-component solder joints.
IPC-qualified technicians perform and oversee all soldering operations.
