Files Requested for PCBA

You will have 3 options to send these files to us:

The first is through our online web page

The second is to send via email at sales@jh-pcba.com referring your order number.

The third is to contact our online sales to inquiry and send to their emails. SALES@come

EPlease include the following files with your order. Please include then in a single ZIP file:

(1) Gerber Files, Please include all the layers files (copper, soldermask, silkscreen, solder paste, drill, outline).

(2) Bill of Materials (BOM) in Excel format. Your BOM should include:

oReference designators.

oQuantity of each part.

oManufacturer part number.

oPart description.

oType (SMT, Thru-Hole, Fine-pitch, BGA, etc.)

oPackage description (QFN32, SOIC, 0805, etc. package is very helpful but not required).

(3) Centroid File, also known as pick and place file. It should include component locations, rotations and reference designators.

BOM (Bill Of Materials)

Kitted

You provide all the parts including the bare printed circuit boards and electronic components, we assemble your boards using our state of the art automated equipment.

Partially Kitted

You provide the hard-to-find parts, the “custom” parts, the parts you have in inventory, whatever parts you have! We help procure the rest of the components, manufacturing PCBs, whatever you don’t provide, then assemble these circuit boards for you.

Full Turn-Key

We manage the entire process from manufacturing the bare printed circuit boars, procuring all parts through assembly and testing as your application requires.

BOM for Kitted orders

BOM for Kitted orders may include following information:

Line#

Quantity of each Part Number

Reference Designator

Manufacturer Part Number

Part Description

Package description (QFN32, SOIC, 0805, etc. package is very helpful but not required)

Type (SMT, Thru-Hole, Fine-pitch, BGA, etc.)

Gerber Files:

Best in format of RS-274X, Gerber Files, Please include all the layers files (copper, soldermask, silkscreen, solder paste, drill, outline).

Centroid File:

Centroid File 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.

So please make sure that all these files have been included and reviewed at your side. Of course we will also review your files before assembly starts to make sure all the information is complete and accurate for assemblies.

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.
