What is PCBA ?

Actually this is a terminology of electronic field, it is abbreviation of Printed Circuit Board Assembly.
PCB is the core of any electronic technology products,from our personal computer and mobile phone in daily life to aircraft in aerospace, missiles in the military, and ships at sea, almost all products that operate on electricity have a PCB.

PCBA Workshop

PCBA is also means the processes of manufacture this core board.This is a complicated and long process,there are multiple units such as R&D and design companies, raw material manufacturers, semiconductor manufacturers, metal parts manufacturers, plastic parts manufacturers, PCB manufacturers, and PCBA manufacturers. However, PCBA manufacturers are usually the final integrators of these units, that is, they integrate the technologies and materials of the previous manufacturers. Finally, the final product is assembled, produced, tested and finally shipped in the PCBA factory. Such PCBA companies are usually the factories behind brand companies, so you may not have heard of them. Only a few large Fortune 500 companies that you may have heard of, such as FOXCONN, which manufactures for Apple in China, and Jabil. PCBADEPT company has more than 15 years experiences in PCB Assembly filed ,our factory has ISO9001 quality certificate system, 6 SMT line , 4 DIP line , 8000㎡ workshop,from PCBA design ,material procurement to PCB assembly,test and final delivery.

PCBADEPT Order Process

PCBADEPT Company How To Ensure Quality?

Firstly during the initial procurement stage, we strictly quote and purchase based on the customer's BOM list and will never use components or raw materials that have not been approved by the customer.

Secondly, if the customer's BOM list includes discontinued or long-leaded materials, our professional engineers will provide compatible models and datasheet to the customer for confirmation or verification before they are used.

Thirdly, during the incoming material inspection stage, we have dedicated quality inspection engineers to inspect the brand, model and specification of the materials, measure the parameters with LRC equipment, and check the PCB soldering pad before production to ensure that the footprint of the materials is consistent with the PCB soldering pad.

▶ In production:
* SPI Solder Paste Inspection
Solder paste inspection can check the solder paste is sufficient and uniform to prevent assembly quality problems in advance caused by poor solder paste soldering
* Online AOI Inspection
The AOI can check the short circuit, offset, wrong solder, reverse solder, false solder, empty solder, incomplete solder, etc. It also can check excessive solder, less solder, continuous solder and solder joints.
* First sample confirm
Check the first China turnkey PCB electronics sample with Gerber, BOM and coordinate files, test it's function with the testing program. Only sample confirmed by PCBA engineer, it can go for mass production.
* Off-line AOI inspection
Check the soldered surface mount assembly for errors, omissions, and false connections.
* X-Ray welding inspection
Inspect the solder joints of invisible components like BGA,QFN
* QC manual inspection
The assembled board is visually inspected to ensure 100 % qualified
* Function test
NPI and the engineering and technical team will based on the customer's product test data, prepare test JIG, test software in advance, and make JIG, set up a test environment to conduct electrical parameter tests or functional tests on the products. Any defective products found will be repaired to ensure 100% quality products to delivery.
* MES system(Manufacturing execution system)
Since every material received and produced in the workshop,all are tracked by MES system.

PCBA Capability

Item	Item name	Capability
1	Delivery time	Our assembly time ranges from 24 hours to several weeks. Please choose the appropriate assembly time based on your project schedule and budget. Due to the complexity of the turnaround time for PCBA services, our policy is that after all components are ready and all PCB files (Gerber files/other PCB files, etc.), (coordinate files, i.e., PNP files, or XY data or other format files), BOM and all other necessary data or documents/images/photos are prepared, Let's start our assembly work.
2	Specification of surface mount components	Passive components: We can accept components as small as 01005, 0201, 0402, etc
		BGA: We have the capability to handle 0.35mm pitch BGA for rigid PCBS and 0.4mm pitch BGA for flexible boards through X-Ray testing. (Specific details can be confirmed according to the circuit board design.)"
		Fine-pitch parts: We can assemble fine-pitch parts of 0.20mm ± 0.02mm
3	Loss rate	Capacitor and resistor: 0.3%, Chip: 0%
6	PCB Size	Min: 20mm20mm / Max: 450450mm
7	PCB Type	Single side,double side hard board, Flexible board and Rigid Flex PCB
8	Repairing and rework	We can assist customers in troubleshooting and rework based on the schematic diagram, supporting the rework of QFN and BGA packages
9	Stencil	We use laser cutting of stainless stencil to ensure the high reliability of fine-pitch and BGA components. Nano-coatings can be provided upon request.
10	Function test	Support,appearance inspection, online testing (ICT), flying probe testing (FPT), automatic optical inspection (AOI), automatic X-Ray inspection (AXI), aging testing

PCB Assembly Cases

We have an experienced and professional quality inspection team that can conduct appearance inspection, functional inspection, etc. on each material to ensure that every material entering the warehouse is qualified.
