Mixed PCBA Capabilities
1. What Is Mixed PCB Assembly?
Mixed PCB Assembly has combined the characteristics of surface mount technology (SMT) and through-hole technology (THT), hence why its name comes. Technicians mainly apply this technology in applications that need a combination of THT and SMT. This kind of PCB assembly does not require any solder paste. Venture Electronics is one of the most experienced and reliable manufacturers in China. We have the capabilities to assemble single-sided, double-sided, and multi-layer circuit boards with mixed PCB technology.
At Venture, we have a team of experienced engineers, technicians, and sales motivated to assemble great and efficient printed circuit boards using hybrid technology. Our experience and knowledge give us a good understanding and practice of the PCBA services. That is why we know our customers’ exact requirements so quickly. May I know if you have any mixed technology PCBA services requirements? If you have such demands, then you are at the right place. Get in touch directly with our teams, and let us discuss the job. We will be pleased to help you with your demands.
2. Mixed PCB Assembly Capabilities
Here are the mixed assembly capabilities.
| Item | Item Name | Mixed PCB Assembly Capabilities | |
| 1 | Lead Time | Our service ranges from 8- to 48 Hours for prototype and small volume PCB assembly projects. Since each project’s complexity is different, our tum-time starts from the time that all the components are ready. These components are PCB files (Gerber files/other PCB files, etc.), Centroid (Pick & Place PNP file, XY Data or files in different formats), BOM, and all the other necessary data or documents/images/photos. And then we start our assembly work. | |
| 2 | Parts Source | Kitted(Consigned) | Our Kitted PCB Assembly requires you to supply all the components and ship them to us. |
| Partial Kitted | Our Partial Kitted PCB Assembly service, means you offer the main components, and we source the rest of the other parts for you and return you your assembled boards. We will ask for your approval on every detail of the components concerning price, quality, and availability. | ||
| Turnkey | We do our Turnkey PCBA service based on our worldwide network of components sourcing. Our team sources from reliable suppliers such as Digikey/Mouser/TME/Element 14 and local certificated distributors. We will always ask for your approval before making any decisions on equivalent components. | ||
| 3 | Assembly Options | We offer Surface Mount (SMT) Assembly, Thru-Hole (THT) Assembly, and Mixed Assembly. | |
| 4 | Types of Solder | We offer Surface Mount (SMT) Assembly, Thru-Hole (THT) Assembly, a hybrid of both{ Mixed Assembly), BGA & QFN Assembly, and Kit. | |
| 5 | Stencils | We use laser-cut stainless steel stencils to ensure high reliability for fine pitch and Ball Grid Arrays components. | |
| 6 | Minimum Order | Any Qty. Our minimum order qty is one pcs. We specially focused on prototype (1-10pcs), small-batch(10- 100pcs) assembly and low volume PCB (100-500pcs) assembly | |
| 7 | Board Dimension | Min Board Size: L50mm x W50mm (smaller than this size needs to be panelized) Max Board Size: L774mm x W710mm | |
| 8 | Board Shape | We can assemble boards in Rectangular, circular, and any other odd shapes. For PCB shapes other than rectangles, Please penalize the bare PCBs in an array, and add break-away fields at the two longer paralleled edges of the panelized boards. In this way, we can assemble panels by the machine. Our engineers can help you with PCB penalization if needed. | |
| 9 | Board Type | We can assemble Rigid Boards (FR4, CAM, etc. ), Metal Core (Aluminum, copper) Boards, Flex boards ( Flex PCB). Rigid-Flex Board (Rigid-Flex PCB) | |
| 10 | IC Programming | DIP, SDIP QSOP, SSOP, TSSOP, PLCC, QFN, MLP, BGA, CSP, SOT SOP, MSOP, TSOP, QFP, MLFDFN | |
| 11 | Inspections | Visual inspection: general quality check. X-ay Inspection: reviews for BGAs, QFN, and bare circuit boards. AOI Testing checks for solder paste, 0201 components, missing components, and polarity. | |
| 12 | Functional Testing | Test software, Design For Assembly, Functional Testing(FCT) Avoid assembly issues, Correct component failures, Trouble-shooting program practical test will follow your test procedures. | |
3. Mixed PCBA Equipment
Venture Electronics can offer hybrid technology rapid prototyping and low and high-volume PCB assembly. Following is the fully automatic assembly equipment we used in the assembly process:
- Wave and selective wave soldering machines.
- Automated multi-stage aqueous cleaning.
- Automated optical inspection.
- X-ray inspection.
- First article inspection.
- Functional testing/IC programming.
- Injection molding.
4. Advantages Of Mixed PCB Assembly
- Generally, technicians can assemble more significant components with high power handling capabilities and more minor elements with very effective SMT components on the same board.
- Technicians can install the components on both sides of the PCB. Then you will have more space to accommodate other parts. The resulting equipment will perform better in processing speed and power handling.
- This hybrid technology is installed and reworked with 100% X-ray inspection.
5. Issues Before Mixed PCBA
Before starting the mixed PCB Assembly, some design issues were of particular concern:
Firstly pay attention to the maneuvering of the insertion machines and PTH devices requiring extra room on the PCB. The thermal profile issues that affect the soldering process should be solved when determined to use lead-free techniques to assemble the circuit boards.
6. Applications Of Mixed PCB Assembly
Generally, Technicians popularly apply the mixed PCB Assembly in many industries. Below are some significant applications:
- LED Lighting Products.
- Video Processing.
- Communication Hardware.
- Sensor Boards.
- Industrial Controller Assemblies.
- Smartphone Accessories.
- Server boards.
