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:
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.
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:
Design priorities include miniature footprint (down to 10 mm × 10 mm), multi-year battery life, robust RF performance, and reliable operation in harsh or wearable environments. IoT PCBs frequently use high-density interconnect (HDI), rigid-flex or fully flexible substrates, and ultra-thin materials to meet these demanding requirements.
