Small and Serial Production
We carry out both small and serial installments in our production

Fast Turn Assembly
Due to powerful equipment, the installation of large-scale batches takes the shortest possible time

Installation site services

• Automatic/mixed assembly of SMD components (lead, lead-free, and combination assembly)

• Automated output assembly (production of LED panels)

• Assembly of prototypes and small batches (semi-automatic and manual assembly)

• Wire processing, harness and cable assemblies manufacturing

• Moisture protection with varnish and filling with compound

• Manual installation of outlet components

• Stencil production

• X-ray quality control of soldering

• Surface and outlet mounting

PCB Assembly Services: Stages of installation
Solder paste application

Much attention is paid to this stage since the main defects in the technological chain arise precisely when problems with the application of solder paste. We use screen printing printers to apply the solder paste.

Installing components
To install the components, we use two types of automatic insertion machines: revolving and gantry. They combine maximum precision, the ability to adjust settings, and high production volumes.

SMT Assembly Line

• Allows to reduce the length of the leads and increase the density of the arrangement of components on the boards, which significantly improves the quality of the transmission of weak and high-frequency signals;

• Increased manufacturability and productivity;

• The speed of installing components on a printed circuit board - 2000 components per hour;

• The ability to manufacture small-sized printed circuit boards with the installation of small components.

Line capabilities:
• Piece and small-scale assembly of printed circuit boards;

• Installation of all kinds of SMD components (0201, 0402, BGA, QFN, etc.);

• Replacing components on already soldered boards.

Technical requirements:
1. Requirements for PCB blanks:

• Thickness from 1mm to 5mm;

• Dimensions of the PCB blank: for an automatic solder paste dispenser no more than 250mm x 250mm (for larger sizes there is a manual solder paste dispenser); for an automatic installer, the maximum size is 500mm x 500mm;

• The presence of technological fields on the workpiece, at least 5 mm wide.

2. Equipment requirements:

• Components for the manufacture of boards are accepted only in their original packaging (tapes, pencil cases, pallets);

• It is possible to use the contractor's components

3. Requirements fms RC plane for design documentation:

• Dor automatic mounting of boards, GERBER files are accepted for each technological layer of the board in the RS-274-X (mm, 3.3) format, indicating the layer name, project name, date, type, and class of the board;
• When ordering, the nomenclature, quantity, type, and a class of boards, the manufacturing program, and the specification of design data must be indicated.

Assembly of printed circuit boards is one of the main services that our company provides.

Thanks to high-tech equipment, automated BGA assembly lines with a total capacity of up to 160,000 components per hour, modern soldering equipment and materials, KingFord PCB allows you to carry out all types of PCB assembly, as well as the entire cycle of related work:

• Urgent assembly of printed circuit boards;
• Serial assembly of printed circuit boards;
• Production of prototypes pcb assembly;
• Functional testing;
• Separation of boards after installation;
• Lead-free installation;
• Tracing of printed circuit boards.
