1.BARE BOARD PRINTED CIRCUIT BOARDS
A bare board PCB (printed circuit boards) and the bare board testing play critical roles in PCB creation. Bare board, is the PCB before the electric components or through holes are placed on it. A bare board printed circuit boards are comprising of:
*Substrate
*Metal Coating
*Conductive Pathways
CAPABILITIES OF BARE CIRCUIT BOARDS
Our capabilities include designing bare boards to your bespoke needs to that they can support the components that you require.
In addition, our bare board (PCB) also help you in panelization as well as placing your Printed circuit board to larger boards.

| Bare Board Testing | Isolation Testing: This means verifying that the required resistance between two separate electrical connections is met. Continuity Testing: Which involves verifying there are no open points within the circuit. |
Multilayer PCB
BENEFITS OF MULTILAYER PCB FABRICATION
The demand for multilayer PCBs is on the rise; not without reason. Being small and light in weight, they find extensive application in a range of industries. Some of the major benefits of multilayer PCBs include:
*Small Size and light weight:
A big advantage that comes with multilayer PCBs is that they are inherently small and light in weight and therefore lend themselves to portability. With miniaturization on the rise as far as a whole lot of appliances go, this is a big plus in favor of multi-layered PCBs.
*High-quality:
In terms of quality and deliverables, they tend to be far superior and reliable compared to single or double-layered PCBs. That they are also more durable is an added perk!
*High on flexibility:
Where flexible construction techniques are used; what results is flexible multilayer PCBs. This works very well in applications where bending and flexing is a desired trait.
*Powerful:
With multilayer PCBs being high-density and incorporating several layers, they lend themselves to high capacity and speed.
*Single connection point:
Multilayer PCBs work as one cohesive unit and therefore need a single connection point. This is a big advantage even when it comes to the design of the electronic product especially where miniaturization is key.
LED PCB
As an experienced LED PCB Manufacturer at Singo, we bring complex designs to life. Our extensive capabilities in LED printed circuit boards include:
*Rigid, flexible as well as rigid flexible boards for LED.
*Metal Core LED circuit boards
*Embedded LED PCB
*SMD LED circuit boards
*A wide range of finishes - SMOBC/HASL, electrolytic gold, electroless gold, electroless silver, immersion gold, immersion tin, and OSP
*Option of base plate - Copper or Aluminum
*Choice of PCB Core - FR-4, Epoxies and aluminum laminated with copper
*Dielectric thickness: .003"
*ROHS compliant/Lead free assemblies
*Automated Optical PCB Inspection, Electrical testing and sample inspections
METAL CORE PCB
A metal core PCB also referred to as a thermal PCB and MCPCB, differs from the traditional FR4 printed circuit boards in that incorporates a metal material as its base. With a thermally conductive dielectric layer, the prepeg dielectric ensures that heat is transferred to the base plate. The base plate, usually made of aluminium or copper, in turn, offers mechanical integrity while transferring the heat to the mounting surface or to the air. With the heat diverted away from the printed critical board components, thermal management is ensured.
What the PCB metal core ensures, therefore, is:
*Proper thermal management
*Improved product reliability
*Improved mechanical durability
Our capabilities in metal Core PCB span the following:
*Aluminium, Copper as base material
*Single Layer, Chip-on-board, Double Sided, Double Layered and Multilayer Metal Core PCB
