What is Communication Mainboard PCBA? 

In the realm of business and electronics manufacturing, the Communication Mainboard PCBA refers to the Printed Circuit Board Assembly (PCBA) that serves as the backbone of communication mainboards.  PCBA is the professional terminology for the process of mounting and soldering electronic components, such as integrated circuits, resistors, and capacitors, onto a printed circuit board (PCB).  The PCB provides the foundational structure for supporting and interconnecting these components through intricate conductive pathways.

If you are seeking a preeminent manufacturer for communication motherboard printed circuit boards (PCB/PCBA), JH PCBA stands as your unparalleled choice. Our communication motherboard PCB products are paramount to communication stability and usage, adhering stringently to GMP standards, rigorous safety and reliability protocols. We ensure the utmost quality and efficiency in production, meticulously guarding against any potential contamination or defects. JH PCBA boasts ISO9001 and ISO14001 fundamental certifications, and we have also successfully obtained CE and RoHS certifications, demonstrating our unwavering commitment to quality and safety.

We are an experienced partner in the communication industry, and we are highly appreciated by our customers for maintaining transparency in the production process and strictly following international standards.

Q1. What service do you have?

We can offer you PCB Design, PCB board manufacturing, Components or Parts Source, Surface Mount (SMT), Thru-Hole (THT),hybrid of both, Functional Test, Wire Soldering etc. one stop PCB&PCBA service.

Q2. Is JINHUA a factory or trade company?

JINHUA Technology is a one-stop PCB and PCBA factory with over 13 years’ experiences.


Q3. What is needed for quotation?

Gerber file and Technic requirements (material, surface finish treatment, copper thickness, board thickness, and so on.)


Q4. What file formats do you accept for production?

Gerber Files+BOM File+Centroid File(other names maybe: aka Insertion, Pick-N-Place, or XY Data)

Gerber Files: including files: copper (track), soldermask, silkscreen, solder paste, drill, outline files


Q5. Do you assemble BGA? Any special requirement on this?

Yes, we have the ability to handle BGA of 0.25mm pitch with X-ray testing. For BGAs, there are two designs with via on pad and via near pad connected by shorter trace. We need to tent and fill any vias near pad of the BGAs with solder mask to ensure the soldering quality. But for vias on pad, we need to fill via with resin to make sure good soldering quality.


Q6. How do you handle the excessive and unused parts?

Excessive parts do exist because we will ask for some percentage of overage for consigned/kitted orders, or we will buy more for the same purpose for those Turn-key orders. You can either ask us to ship back to you these unused parts together with the loaded boards, or keep them in our shelf for your next order. All up to you.


Q7. What is your testing policy and how you control the quality?

As to PCBA production, there are automated optical inspection (AOI) for each batch, X-ray inspection for BGA parts, first article inspection(FAI) before mass production.

Q8. How long does it take for PCBA quote?

Normally 24 hours to 48 hours as soon as receive internal engineer evaluate confirmation.


Q9. MOQ?

There is no MOQ in Jinhua Technology. We can offer prototype, expedite prototype, small& medium amount, big amount pcba service.

AS to PCBA production, there are automated optical inspection(AOI) for each bacth,X-ray inspetion for BGA parts, first article inspection(FAI) before mass production.

6. What are the Factors Affecting PCB Cost?

The following listed are the key factors but not limited:

The quantity and size of the PCB.

The Number of Layers

Effective Panelization - Some board sizes and shapes can offer up to 80% Usable Panel Area, with very few “dead spaces”, while others some down to 50%. This would affect your price.

Number of holes the boards is drilled on sophisticated NC drilling machines. These machines are quite expensive and the machine time is expensive too, so less holes means less machine time for drilling and lower cost.

Number of Hole Sizes - the slowest operation in drilling is the tool exchange. Usually the boards are drilled at very high RPM values, up to 60-80.000 rpm. To change the tool, the machine has to stop the spindle, so we must wait until the tool stops rotating. Once the drill action has stopped, the machine must move to the drilling rack, replace the old tool, get new tool, move back to board drill position, drive the spindle again, and wait for the RPM value to reach the set point for the new tool. Each tool change takes approximately the same time as drilling 100-200 holes. Try to minimize the number of drill tools as much as possible. It is best to standardize any holes with diameter differences of only a few mils, if the change will pass your required tolerances. 

PCB Laminate Material - when you intend to manufacture your board in volume, the right choice for the board laminate can save a lot of money. For instance despite the superior characteristics of FR-4, all consumer electronics today still is manufactured on old paper FR-2 laminates as they cost two times less expensive than FR-4.

Trace Width / Part Spacing requirements – these characteristics are in close relation to the manufacturing yield. For instance, if your traces are wide enough (>20mils) the board can be manufactured with etch resist single silkscreen printing operation instead of dry film lamination, exposure, developing.

Special board requirements, Controlled Impedances, Via in Pad, Blind / Buried Vias, Microvias, etc. – again, these requirements affect the manufacturing yield.
