PCB Assembly needs a few files in order for us to start your PCBA work. Please Send the following files to us in proper format. You will have
two options to send these files to us, one is through our online webpage, the other is to send via email at sales@multitech-pcb.com referring your
order number and put the email Subject as “Files for order number 123456”
Please get ready your BOM files, Gerber files and Centroid files for your PCBA service. BOM for Turn-key and partial Turn-key may contain
a little more information that the one for consigned/kitted. Please check in detail.
Consigned BOM:
In a consignment model, the supplier provides materials to the manufacturer or distributor, but ownership remains with the supplier until the materials are used or sold.
The BOM lists details of these materials, including quantities and specifications, but usually does not include the cost of the materials, as the cost remains with the supplier until the materials are consumed.
Kitted BOM:
In a kitted model, multiple parts are pre-packaged together as a complete kit or assembly unit for production or sale.
The BOM lists all individual parts and quantities that make up the kit, and these parts are usually packaged or organized together for direct use in the production process.
Turn-key BOM:
In a turn-key project, the BOM includes all the components and materials required for the entire project, from start to finish.
The goal is to deliver a fully functional system or product to the customer, with all necessary parts and assemblies included.
This BOM provides a comprehensive list of everything needed to complete the project, often with detailed specifications and quantities
Partial Turn-key BOM:
In a partial turn-key project, the BOM includes only the components and materials for specific parts or phases of the project.
The customer may need to supply or source additional materials or parts independently for other aspects of the project.
This BOM focuses on the subset of materials required for the particular portion of the project being handled, rather than the entire system.
Gerber files are a standard set of files used in the electronics industry to communicate the design of printed circuit boards (PCBs). They contain detailed information about the PCB's layout, including:
Copper layers: The traces and pads for electrical connections.
Silkscreen layers: Text and symbols printed on the surface of the PCB.
Drill files: Locations and sizes of holes for components and vias.
Solder mask layers: Areas covered with solder mask to prevent solder from flowing where it isn’t needed.
These files are essential for PCB manufacturing and assembly, as they provide all the information needed to create the physical circuit board from the design.
Centroid is the special file for assembly used for quickly programming the assembly machines. This is also known as aka Insertion, Pick-N-Place, or XY Data. Some of the CAD tools will automatically generate this file and some not, but you may need to modify the file and then generate the Centroid file. The Centroid file describes the position and orientation of all the surface mount parts, which includes the reference designator, X and Y position, rotation and side of Board (Top or Bottom). Only surface mounting parts are listed in the Centroid.

In order for us to properly assemble your printed circuits boards, we strongly recommend you send all other documents or information related to the boards to us, which may include your assembly drawings, special assembly instructions, and even images or photos of your work. These information helps us better understand your assembly needs, correcting some ambiguous or even mistaken placements, and ends up with an excellent job. Send them to us, though normally not required by assemblers.
Proper SMT machine setup and operation requires parts overages. Unused and excessive parts supplied by you or purchased by us will be packaged and returned to you with the assembled boards.
SMT parts which are not supplied on reels should be on one continuous strip of tape.
If you need to assemble the same SMT part in different boards, do not cut them into strips, please keep them in the continuous strip of tape or on the reels.
Resistors, Capacitors, Diodes (0603, 0805, 1206, 2225, SOT, SOD, MELF - packages) require a minimum of 50 pieces and have to exceed the required quantity by 30 pieces. (e.g.: assemble quantity 40 pieces – we will need 70 pieces – this meets our minimum of 50 pieces plus 30 pieces over assemble quantity).
Resistors, Capacitors, Diodes (0201, 0402, miniMelf, miniature packages) require a minimum of 100 pieces have to exceed the required quantity by 50 pieces. (e.g.: assemble quantity 80 pieces – we will need 130 pieces- this meets our minimum of 100 pieces plus 50 pieces over assemble quantity).
A small number of excess(1-5 pieces based on the total quantity of assemblies) is requested for expensive parts such as IC, BGA, QFP, Connectors, etc., this will ensure smooth assembling and shipping your assembled boards on time. If you have any question or doubt, please send more extra or contact us for answers.
If your PCB dimension is smaller than 50mmx100mm, or if your PCB is of any shapes (circular, or odd shape) other than rectangle, your boards must be panelized in an array for assembly. As we also fabricate your PCB for you, so once we start fabricating your boards we will have the panelization file (solder paste data), we will transfer the data to PCBA department to create the stencil to match the panelized PCB.
If the clearance between the board’s edge and copper features is less than 3.5mm (138mil), or your boards need to be panelized for some reason, Break-away rails (Break-away tabs) must be added at the two longer paralleled edges of the boards to ensure that the boards can be assembled by the machine.

We need Gerber files, Centroid data and BOM for your PCBA orders. As have already placed your PCB order with us, actually you only need to send the latter two if your PCB Gerber files have included the layers of silkscreen, copper track and solder paste. If your PCB Gerber files are missing any of the above-mentioned three layers, please resend them, as this is the minimum request for PCBA. For the best possible result, please also send assembly drawings, instructions and photos to us to avoid any ambiguous and even mistaken placement of parts, though these are not required by most of the assemblers.
Centroid is the special file for assembly used for quickly programming the assembly machines. This is also known as aka Insertion, Pick-N-Place, or XY Data. Some of the CAD tools will automatically generate this file and some not, but you may need to modify the file and then generate the Centroid file. The Centroid file describes the position and orientation of all the surface mount parts, which includes the reference designator, X and Y position, rotation and side of Board (Top or Bottom). Only surface mounting parts are listed in the Centroid.
We hope you can mark on any individual package or box with the corresponding line number on BOM, manufacturer’s part# or customer’s part#, quantities. A detailed packing list is preferred to enable us to count and check upon receipt of your parts.
Proper SMT machine setup and operation requires parts overages. Unused and excessive parts supplied by you or purchased by us will be packaged and returned to you with the assembled boards.
SMT parts which are not supplied on reels
should be on one continuous strip of tape.
If you need to assemble the same SMT part in different boards, do not cut them into strips, please keep them in the continuous strip of tape or on the reels.
Resistors,
Capacitors, Diodes (0603, 0805, 1206, 2225, SOT, SOD, MELF - packages) require a minimum of 50 pieces and have to exceed the required quantity by 30 pieces. (e.g.: assemble quantity 40 pieces – we will need 70 pieces – this meets our minimum of
50 pieces plus 30 pieces over assemble quantity).
Resistors, Capacitors, Diodes (0201, 0402, miniMelf, miniature packages) require a minimum of 100 pieces have to exceed the required quantity by 50 pieces. (e.g.: assemble quantity 80
pieces – we will need 130 pieces- this meets our minimum of 100 pieces plus 50 pieces over assemble quantity).
A small number of excess(1-5 pieces based on the total quantity of assemblies) is requested for expensive parts such as IC,
BGA, QFP, Connectors, etc., this will ensure smooth assembling and shipping your assembled boards on time. If you have any question or doubt, please send more extra or contact us for answers.
Yes. This practice is called partial Turn-key. You can supply some parts, and we source the rest of the parts on your behalf. We will ask for your approval for anything that is not sure at our side. In case parts crossing or substitution is needed, we will again ask for your final approval.
Yes, We have the ability to handle BGA of 0.25mm pitch with X-ray testing. For BGAs, we need to tent any vias under the BGAs with solder mask to ensure the soldering quality.
Excessive parts do exist because we will ask for some percentage of overage for consigned/kitted orders, or we will buy more for the same purpose for those Turn-key orders. You can either ask us to ship back to you these unused parts together with the loaded boards, or keep them in our shelf for your next order. All up to you.
Our online instant quote system gives the rough idea of the cost of PCBA which include the tooling, laser cut steel stencil, and labor. In case of Turn-key or partial Turn-key PCBA, the cost of parts will be added. We do not mark up on the parts that we will source for you.
Due to the complexity of how to determine the turn time of PCBA services, our policy is that turn-time begins immediately after all the parts and PCBs are ready and all the PCB files (Gerber files/other PCB files, etc.,) , Centroid (Pick & Place PNP file, or XY Data or files in other formats), BOM, and all other necessary data or documents/images/photos are complete for our assembly work.
Yes. But we also offer leaded PCBA services.
Panelization is needed when your PCB dimension is smaller than 50mmx100mm, or when your PCB is of any shapes (circular, or odd shape) other than rectangle, your boards must be panelized in an array for assembly. As we also fabricate your PCB for you, so once we start fabricating your boards we will have the panelization file (solder paste data), we will transfer the data to PCBA department to create the stencil to match the panelized PCB.
If the clearance between the board’s edge and copper features is less than 3.5mm (138mil), or your boards need to be panelized for some reason, Break-away rails (Break-away tabs) must be added at the two longer paralleled edges of the boards to ensure that the boards can be assembled by the machine. This enables the boards can be processed by the SMT machine.
Defects and problems may occur from time to time, as PCBA is a complex work which involves many details. If you find any defects or problems, please let us know immediately, and we will evaluate and review the problems, and we will make a decision of how to remedy. We will either repair/rework or remake your boards. In case we need the defective boards, we may ask you to send them back to us. We guarantee a functional board in your hand!
IPC-A-610 Class 2.
As we need to source all the parts for Turn-key orders, the turn time largely depends on how quick we can get all the parts. We will let you know through everyday email communications. Before all parts are ready, we will fabricate the PCBs and start to make the stencil so that we can start assembly immediately after we get the parts.
