In this article, we will explore the PCB assembly service provided by a leading PCB company, JLCPCB.

JLCPCB has become a leading global PCB manufacturer with over 15-year continuous innovation and improvement based on customers need. It offers best quality PCB prototypes and PCB assembly service at a very affordable price range.

The price of 5 Pcs of single layered, 2-layered and 4-layered PCB’s is only $2. However, the board size also matters here. For single layer and two-layer PCB (100x100mm) and for 4-layer PCB (50x50mm).

This means you can get a basic PCB just in $2. Though there  is a list of quality of boards, material type, thickness, colour and surface finishing we can choose from and the price will change according to that. But getting 5pcs of PCBs just in $2 is still a steal deal.

Just like the PCB prototypes, the SMT assembly service provided by JLCPCB is also great, durable and most importantly the cheapest one.

How to place an order ?

For this you need just 3 files

1) Main Gerber file (Contains PCB data)

2) BOM File (Bill of material, component cost)

3) CPL file (Pick and place file- describe orientation of components)


In the first step, be ready with your design (using EASYEDA )and the PCB layout with no errors. Then you have to download the GERBER files. To do this, go to PCB design window and select file, then Generate Fabrication File (GERBER). This will download a zip file with the GERBER files.

Then you will have to click on Export BOM file and Export Pick and Place File. Both the files will be Excel files with the components data and the coordinates. So now you will have the zip file with the GERBERS, the BOM and CPL files.

Step- 2

Now, visit JLCPCB site with the above three files ready with you. Then click Get Instant Quote on the STM Service page. On the first order page you will have to upload the GERBER file.

Once the file is uploaded, select how many PCBs you want and fill up all the required fields.

On the next page upload the BOM and CPL files.

Then, you will get the list of all the components you will have on the PCB . Confirm each one to make sure that each one is the correct component. Then confirm and click next.

Finally, you will get a review of the order and you can see the component placement. Check if everything is ok then click order. Make the payment and wait for nearly 1 week to get your PCB in hand.
