That's why we've revolutionized our PCB Assembly Quote System with an advanced, automated solution. Say goodbye to waiting for human review – now, you get instant, transparent cost estimations for your PCB and PCBA needs, streamlining your ordering process from start to finish.

In the past, our team would manually review and process each quote, which could sometimes delay the process. We recognized the need for a faster, more streamlined service. Hence, we've invested in this automation that will allow us to provide instant, accurate quotes.

The new system uses a sophisticated algorithm to calculate costs based on input files, ensuring you get the most precise quote in real-time. This reduces the lead time and allows you to make quick decisions, accelerating your production process.

What Are Files Requirements for PCB Manufacturing or Assembly?

For PCB Manufacturing

‌Gerber file ‌

This is the most commonly used file format, which records the information of each layer of the PCB in detail, including the copper layer, silk screen layer, solder mask layer, etc. Gerber files are saved in RS-274X format, which has high compatibility and stability, ensuring that the design information is accurately transmitted between different systems and devices. ‌ Learn more about <Gerber Files for PCBs: Creating, Viewing, and Converting>

Please note that different PCB manufacturers may have certain restrictions on the file size. For example, NextPCB requires the Gerber file format to be: Only ZIP or RAR files, Up to 50MB

‌Drill file

Contains the location information and aperture value of all drill holes. Drill files are very important for manufacturers because PCB boards need to be drilled, and the accuracy of drilling information directly affects the installation of components and the reliability of circuit connections. ‌

For PCB Assembly

In addition to the files required for PCB manufacturing, PCB Assembly also requires the following files:

‌BOM file ‌ (Bill of Materials)

That is, the bill of materials, which records the detailed information of all components on the PCB board, including model, specification, quantity, etc. BOM files are crucial for sample manufacturers because they help prepare components, arrange production plans and perform cost accounting.
Note: The format Only support XLS or XLSX or CSV files, Up to 5MB

Centroid File

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. Learn more about <How to Create a Centroid(Pick and Place) File Instantly?>
