Home Automation IOT Printed Circuit Board Assembly with Gerber File
and BOM List
♦ What is BOM List?
A BOM List (Bill of Materials list) is a structured document that
enumerates every component, raw material, sub-assembly, fastener,
adhesive, label, etc. required to build one complete unit of a
product. For each line item it normally specifies reference
designator(s), manufacturer part number, approved alternates,
package type, value/tolerance, quantity per board or per product,
procurement status and sometimes cost and lead-time. In electronics
manufacturing the BOM list is the master recipe that purchasing,
SMT programming, kitting, IQC, costing and logistics all follow;
without an accurate BOM list a PCBA cannot be quoted, built, tested
or repaired correctly.
♦ What is IoT Printed Circuit Board?
An IoT Printed Circuit Board (IoT PCB) is a compact,
ultra-low-power circuit board specifically engineered to be the
hardware core of an Internet-of-Things device. It integrates:
Micro-controllers / SoCs for local processing
MEMS sensors (temperature, humidity, motion, ambient-light, gas,
etc.)
Wireless connectivity modules (Wi-Fi, BLE, Zigbee, LoRa, NB-IoT,
LTE-M)
Efficient PMICs, DC-DC converters, coin-cell or energy-harvesting
inputs
Antennas, matching networks and high-frequency controlled-impedance
traces
Design priorities are miniature footprint (down to 10 mm × 10 mm),
multi-year battery life, robust RF performance, and reliable
operation in harsh or wearable environments. To meet these goals
IoT PCBs frequently use high-density interconnect (HDI), rigid-flex
or fully flexible substrates, ultra-thin FR-4 or polyimide
dielectrics, and embed passives or even antennas in the inner
layers. The finished board is the physical platform that lets the
device sense, compute, store and securely transmit data to cloud or
edge servers, forming the backbone of smart-home, industrial,
medical and agricultural IoT application.
♦ Types of PCB Assembly Services:
- Turnkey PCB Assembly: Full service (PCB fabrication + component
sourcing + assembly).
- Partial (Consignment) Assembly: Customer provides components;
the assembler handles soldering.
- Prototype Assembly: Low-volume assembly for testing designs.
- High-Volume Production: Mass production for commercial devices.
