PCB Assembly

Quick Turn PCB Assembly


PCB assembly is our core offering in electronics manufacturing. As a full-service electronics contract manufacturer, we provide SMT assembly services, through-hole assembly, and testing following UL, RoHS, and ISO standards.

We offer full turnkey solutions for new product introduction (NPI), rapid prototyping, and high-volume PCB manufacturing. For the customized assembly line, Mefron's facility is fully equipped with cutting-edge machine support for almost every industry standard. We do SMT assembly, through-hole assembly, and a combination of both. We are capable of assembling rigid, flexible, and rigid-flex PCB assemblies.

PCB Assembly Process

Design For Assembly (DFA)

Designing PCBs in a way that is most suitable for assembly while keeping the end product in mind. We consider part and trace spacing, component selection, board size, component placement, and RoHS and non-RoHS-compliant assembly.


SMT PCB Assembly

Automatic PCB Assembly Process

1.

Solder Pasting:

Solder paste is applied precisely onto the PCB with the help of a cutting-edge printing machine. Automated processes reduce the cost of high-volume production.

2.

Pick and Place:

Our high-speed pick and place machine is capable of 54000 CPH. Its built-in auto and hybrid calibration ensure accuracy of placement at a very high level.

3.

Reflow Soldering:

Each PCB goes through 8 bottom and 8 top heating zones with a maximum temperature of 350 °C, and two cooling zones ensure the solder bonds are firm.

4.

Inspection & Testing:

Mefron has a flying probe tester, and the IR-based BGA rework station, and our experienced specialists can test/repair any complex PCB manually and automatically.

5.

Cleaning:

The PCB is well-cleaned to remove dust and moisture before packaging.


Through-Hole Assembly:

Component Placing:

Solder paste is applied precisely onto the PCB with the help of a cutting-edge printing machine. Automated processes reduce the cost of high-volume production.

Inspection and Rectification:

Our high-speed pick and place machine is capable of 54000 CPH. Its built-in auto and hybrid calibration ensure accuracy of placement at a very high level.

Soldering:

Each PCB goes through 8 bottom and 8 top heating zones with a maximum temperature of 350 °C, and two cooling zones ensure the solder bonds are firm.

Our PCBA Focus Areas


24-hour Rapid Prototyping

We are thrilled to take on your prototyping challenges and are ready to ship within 24 hours. No matter how complex a design you have, we make sure its functionality and manufacturability are good as early as possible.

Full Turnkey PCB

From design to testing, global supply chain management enables us to manufacture full turnkey PCBs with a focus on quality and affordability. We take extreme care on the assembly line to achieve the standards and quality that your product deserves.

Procuring Components Globally

We go to all possible extents to obtain high-quality components from leading component manufacturers around the globe. And we are flexible with full and partially contracted assembly services.

Additional Services

We give extreme care about the supporting services that go into your product and make it successful. Like, Wire harness, box building, sheet metal fabrication, software loading, packaging, and labeling.

Capability:


Lead Time

24 Hours to a few weeks.

Consigned / Kitted

We prefer you supply all the parts for the PCBA services.

Turn-Key

We take care of sourcing all components for industry-leading manufacturers.

Partial Turn-Key / Combo

You may provide the main components, the rest we will procure.

Assembly Options

Surface Mount (SMT), Thru-Hole (THT), and hybrid of both for single and double-sided assembly.

Types of Solder

Leaded/lead-free (RoHS Compliant) assembly

Stencils

We use laser cut stainless steel stencils to ensure high reliability for fine pitch and BGA components. Nano coating is available upon request.

Component Size

Handling of passive components as small as 01005, 0201, and 0402, as well as BGA components with a 0.25mm pitch, which are tested using X-ray technology. We can also assemble fine pitch parts with a 0.25mm pitch.

Board Dimension

Board sizes ranging from a minimum of 50mm x 100mm, with smaller boards requiring panelization, to a maximum of 250mm x 500mm. We can work with a variety of board sizes to meet your needs.
