General
accordingly.
As a China-based professional PCB manufacturer, all circuit boards are manufactured in China, then ship out to your office.
We’ve shipped PCB boards to customers from over 100 countries in the past 12 years and the number keeps rising each year. Surely we can ship boards to your country.
Our hours of operation are as follows:
24 hours (Monday to Sunday)
Bare board PCB Ordering
Our minimum order quantity of Prototype PCBs starts is 5pcs. However, we can start from any quantity for Standard PCB service.
You can quote bare board PCBs within seconds using our quote system:
Step 1: Enter Standard PCB Quote page if you need many pcb production or PCB Prototype Quote page if you are looking for prototype boards, Input your circuit specifications and your name,your email and the other contact info and then press Submit Button.We will send you the price by email as soon as possible.
Step 2: If you accept the price,we will make you an PI file and then you can make the payment for the deposit.
Step 3: We will manufacture the goods for you at once after we receive the deposit.
Step 4: We will ship the goods to you at once after we receive the balance cost.
Yes, we can work with single PCB files and manufacture boards in panels. To receive pcbs in panels, please tell us your panel type and input panel quantity and size when make the order;
Once an order has been placed, it’s impossible to change quantity. However, you can place a new order to get the additional quantity – no extra tooling cost will be charged. We can arrange combined shipping for these two orders.
Reorder bare board pcbs is pretty easy. You even don’t need to resend files, and no tooling costs will be charged.
A: You only need tell us the PCB number of your PCB Board before and the PI number of your order before and then we can get all the detail and send you the new PI file to let you confirm.
B: If you think the new PI file is no problem,you can make the payment and we will manufacture the goods for you at once.
Note: NO PCB design modification is accepted except for design updates on silkscreen layer & wiring layer. Otherwise, you have to place it as a new order.
Absolutely. You can place a prototype order first. Use either option to check the quality, then inform us whether if you want to move forward to mass production.
Option 1: We can send board images for your basic check and inspection. Once confirmed, you may repeat this order and purchase large quantity. We will ship all circuit boards to you at one time.
Option 2: We can ship boards to your office for comprehensive inspection. Once confirmed, you may order the rest boards.
If you don’t have the file, please let our salesman know by sending email to this email: sales@circuitcardassembly.com (cc your friend on this email, please include your friend’s previous order number) for reorder. We’ll guide you through.
Of course. We can assemble those boards. But the PCB production won’t start until both your BOM and circuit design files are confirmed. If this is acceptable, please submit a quote request on Assembly quote page .The assembly cost will be given within 1-2 working days. With your approval, we’ll guide you to place the assembly order by email.
If you have sent the files and your parameters by our quote system days ago and you have not received any email from us,please click the live chat in the right corner and we will check at once for you.
Sometimes our emails will be transferred into your emailbox’s junk folder, please have a check and add us on your safe sender lists. If you have not heard from us within 2 working days, please talk with us freely by our live chat system for quote status.
Stencil Ordering
The laser cut stencil is more accurate than the chemical etched stencil, but its price is a little higher. It is cut in a trapezium shape while the chemical etched stencil is cut in a blade or sandglass shape. Its aspect ratio is 1:1 while the aspect ratio of the chemical etched stencil is 1.5:1.
You can Email to this email:sales@circuitcardassembly.com for stencil price, make sure you include the order number.
PCB Assembly Ordering
If you’re looking for Prototype service, the min order quantity of PCBs is 5pcs but it’s ok to have only 1pc of assembled board. If you use our Standard PCB service, there is no min order quantity limit.
You have to submit the info to get assembly price. Once quote and BOM are confirmed, we’ll guide you to place the order.
Step 1: Enter PCB Assembly Quote page ,input your circuit specification, assembly requirements, upload Gerber file, drilling file and BOM, contact info and then click Submit quote button.
Step 2: Assembly quote will be sent to your email inbox within 1-2 working days. Please give feedback on the quote.
Step 3: Once the price is agreed, we will send you an Pi file by email. And then please release the payment by you.
Step 4: BOM confirmation and DFM Check will be carried out once order is received. Production begins only after everything is confirmed.
Unfortunately it’s impossible to change. Please submit a new request on PCB Assembly Quote page , we’ll quote based on the updated spec.
Generally it takes 1-2 working days for us to quote assembly projects. Extra time will be required if you ask for large quantity. We’ll send the quote to your email inbox once it’s ready. First of all, please check your email inbox and junk folder for any email sent from us. If no email was found, please reach us at Live Chat in the right corner for assistance.
Step 1: Please send us the email to this email:sales@circuitcardassembly.com to tell us your PCB number and your PI number before and your new quantity and other updated requirements.
Step 2: The updated quote will be sent to your email inbox within 1-2 working days. If the offer is accepted, we will send you the PI file by email and please release the payment.
Step 3: BOM confirmation and DFM Check will be carried out once order is received.
Absolutely. We offer two first article inspection options:
Option 1: We send board images for your basic check and inspection. Once confirmed, we’ll continue assembling your boards. All circuit boards will be shipped to you once completed.
Option 2: We ship boards to your office for comprehensive inspection. Once confirmed, we’ll continue the rest production.
Generally speaking, Option 2 is more expensive and takes longer lead time than Option 1.
With more than 11 years’ experience in this industry, we are specially good at this field.We have built a reliable components sourcing channel.
