Assembly Services

As a professional electronic manufacturing services (EMS) manufacturer China, with capacity in pcb fabrication, parts

sourcing, design and assembly, our specialty ranges from pcb assembly prototype to mid-volume electronics assembly

project on basis of full turnkey assembly, partial turkey assembly and consignment assembly.


Full Turnkey
MADPCB handles the entire process, including PCB fabrication, components sourcing, pcb board assembly and

testing.


Partial Turnkey
Customer supplies selected electronic parts, and MADPCB procures the balance parts, pcb fabrication, pcb assembly and

testing.


Consignment
All electronic parts provided by the customer, and MADPCB handles pcb fabrication, pcb assembly and testing.

• Bill of Materials(BOM)

BOM Sample.xlsx


• Pick and Place(Centroid) file

Pick and Place (Centroid) file.txt


• Assembly Drawing

Assembly Drawing Sample



Valid BOM (Bill of Materials)


• Item Number(optional): this is the Line number in excel. Each type electronic component occupies an item line. If the

  part number is the same, just note this once and note the quantity.

• Manufacturer Part Number(required): Part number indicates exact part you want from the manufacturer or a distributor.

• Designator(required): identifies a part on a pcb silkscreen layer. All of the same part number should be in the same excel

  cell, like ‘C03, C15, C16, C88’, ‘R1, R2, R3, R8, R10, R14, R90, R102, R107’...

• QTY/Borad(required): the quantity of such specific part you need per circuit board.

• Vendor(optional): the distributor who supplies the component.

• Vendor Part Number (optional): When the part info is ambiguity, this should be the exact part number as you would

  order it from that distributor

• Value(optional): resistance, capacitance, inductance and etc., and the tolerance.

• Package / Footprint (optional): electronic component standard package size, can be used to redundancy check. Like

  0201, 0805, SOIC8, SOT23-5.

• Part description/ specs(optional): electronic component description by the manufacturer.

• Manufacturer(optional): the name of the part manufacturer. Specify the full name or its well-known abbreviations.

• Remarks (optional): providing some additional information, like part link, picture, turnkey or consigned, whether it can

  suffer chemical cleaning.


PCBA Testing


• PCBA AOI Test
• In-Circuit Test (ICT)
• Functional Test (FCT)
• IC Programming



Delivery Time


• Delivery Time is the sum of PCB Lead Time, Parts Procedure Time and Assembly Time.
• Lead Time is our printed circuit board manufacturing time, which is differs from the order square meter, layer count,
   PCB material and complexity. (click for
PCB Delivery Time Table)
• Parts Procedure Time is subject to parts stock, whether need importing from abroad, transportation time and etc.
• Assembly Time includes electronic pcb assembly, pcba testing,  pcba cleaning and packaging.
