We operate to the ISO9001:2015 accredited
quality management system. Our quality system ensures we adhere to processes and procedures
commensurate with providing a quality of service demanded by our customers. At Network PCB, we
specialize in developing high-quality PCBs serving various industries segments. Our PCB manufacturing
process is built upon advanced technology equipment and automated processes to ensure quality &
DESIGN RULE CHECK (DRC)
A design rule is a geometric constraint imposed on the
circuit board, semiconductor device, and the integrated circuit (IC) designers to ensure their designs
function properly, reliably, and can be produced with acceptable yield. We ensure that the Design rules
for production are developed by our experienced process engineers based on our process capabilities to
materialize the design intent. Electronic design automation is used extensively to ensure that the
design rules are not violated. DRC practices are followed before any signoff on the design by way of LVS
(layout versus schematic) checks, XOR checks, ERC (electrical rule check), and antenna checks.
AUTOMATED OPTICAL INSPECTION (AOI)
AOI will scan the inner layers to detect short or open
circuits. PCBs and inner layers for multilayers undergo an automated visual inspection depending on the
This inspection device covers the entire PCB and examines it for : Short circuit, Restrictions,
Breaks and Foreign particles.
FLYING PROBE TESTING
The testing of circuit boards is performed after the
manufacturing. The circuit boards are checked with a flying probe, or for larger series we use an
adapter E-Test. The layout is analysed according to the net list (from the Gerber data) for short
circuits and interruptions.
We employ new generation of flying probes aimed at providing
increased test speed, improved access, and greater fault coverage. We use this testing for low-volume
and for prototype circuit boards. Typically the flying probe test validates the line set-up without the
cost and cycle time associated with designing and building traditional bed-of-nails fixtures.
VERIFICATION OF MANUFACTURING TOLERANCES
The production of printed circuit boards is carried out
according to the valid IPC guidelines and relevant standards in addition to various inhouse technical
specifications, that include Pattern tolerances, vias & drills, Cu thickness in vias, Impedance Control,
Printed Circuit Boards with controlled impedance require a
very high degree of accuracy in order to function appropriately. We work with the PCB designers with
their definition of trace impedance and tolerance requirements, to ensure that the specifications are
materialized. We source our materials from reputed manufacturers to ensure that our customers receive
only the highest-quality printed circuit boards that meet all impedance specifications.
