PCB Enclosure Assembly

HX Technology also offers PCB Finish Product Assembly and circuit board enclosure box, including assembly with the outer shell and with a wire connector.


With two circuit board enclosure lines and a specialized warehouse for raw material provided by customers, we will ensure your circuit board enclosure box products meet the highest quality standards for assembly. With consideration of enclosure design for PCB and knowing the finish product structure first, we would set standards for every kind of printed circuit board enclosures we assembly; only with strict criterion and control system to make sure the quality and deliver on time!

Design Guidelines of Printed Circuit Board Enclosures

  • Ensure MCAD and ECAD tools use the same data format. 

  • Select the right component package for the printed circuit board enclosures. 

  • Ensure that the printed circuit board enclosures box fits the board size. 

  • Ensure board cutouts are accurately aligned with component placement. 

  • Understand the environmental hazards of the installation. 

  • Consider the impact on signal transmission. 

  • Select printed circuit board enclosures materials that meet thermal requirements. 

  • Consider equipment tolerances.

What is a Circuit Board Enclosure?

Printed circuit board enclosures is equipment to store and protect printed circuit boards, which can offer a PCB cover. In order to protect the PCB from environmental factors, adding possible consideration of electromagnetic compatibility (EMC), circuit board enclosure box is almost certain that the PCB will be placed in some form of enclosure. Inevitably, the printed circuit board enclosures will interfere with the free flow of air around the PCB and therefore also have an impact on the thermal performance of the system.


Features of Printed Circuit Board Enclosures

The printed circuit board enclosures are completely sealed and has no holes or seams.

The thickness of the printed circuit board enclosures is 2 mm, independent of the housing material.

The printed circuit board enclosures are capable of dissipating thermal energy to the outside environment through convection, conduction and radiation mechanisms.

Safety Distance Between enclosure design for PCB

The production and processing of PCBA for the board and the enclosure design for PCB will generally have safety distance requirements. This distance can ensure that our PCBA board will not be damaged in some harsh environment.


The safety distance between the PCBA board and mounting PCB in the enclosure includes electrical clearance (space distance), creepage distance (distance along the surface), and insulation penetration distance.

I. PCBA board and the circuit board enclosure of the electrical clearance requirements: electrical clearance refers to the two adjacent conductors or a conductor and the adjacent motor shell surface along the shortest distance measured by air. According to the measured working voltage and insulation level, the distance can be decided.

II. PCBA board and circuit board enclosure creepage distance requirements: creepage distance refers to the two adjacent conductors or a conductor and the adjacent motor shell surface along the shortest distance measured by the absolute insulation surface.

III. PCBA board and circuit board enclosure insulation penetration distance requirements: it should be in accordance with the working voltage and insulation application occasions in line with the following provisions.

  • For working voltage not exceeding 50V (71V AC peak or DC value), there is no thickness requirement.

  • The minimum thickness of additional insulation should be 0.4mm.

  • When the reinforced insulation is not subject to any mechanical stress at the normal temperature that may lead to deformation or performance degradation of the insulation material, the minimum thickness of the reinforced insulation should be 0.4mm.


HX will custom PCB enclosure with a safety distance for your use!
