PCB Design & Manufacturing Services

PCB Design & Manufacturing Services

The design of Printed circuit board (PCB) is based on the graph of electric circuit principle, then realize the function the circuit designer need. The design of the printed circuit board mainly refers to the layout design, need to consider various factors such as the layout of the external connections, the layout optimization of the internal electronic components, the layout optimization of metal wire and hole, electromagnetic protection, heat dissipation etc. Good landscape design can save production costs and achieve good circuit performance and heat dissipation performance. Simple layout design can be implemented by hand and complex layout design be achieved with the aid of computer aided design (CAD).

CAD 2D drawing service

CAD 2D drawing service is to conduct mapping according to samples provided by customers, provide corresponding 2D view service or provide corresponding 2D engineering drawing service according to specific requirements provided by customers, so as to provide customers with design review and production and processing customization in accordance with 3d 2D engineering drawing.


CAD 2D drawing refers to the projection direction of product shape or section on x,y or x,z or yz plane respectively, and the corresponding length, width and height dimensions are marked out, so as to express a complete product structure standard through three views and sectional drawing.


Proe 3D drawing service

Proe 3D drawing service refers to providing the corresponding 3D view service according to the samples or specific requirements provided by customers. 3D drawing can vividly present customers' ideas and continuously improve according to customers' requirements until customers are satisfied with 3D drawing.For the internal structure of the product, 3D drawing can be viewed and analyzed, so that customers have a complete understanding of the internal structure of the physical appearance.Customized for late production and an intuitive standard.


ProE 3D drawing software is a 3D drawing software with excellent performance, which can provide x,y and z coordinate views and view various sizes.At the same time, 3D view can be converted into CAD 2D view, which greatly saves the time of drawing CAD 2D picture. As soon as 3D picture is completed, 2D picture will come out.It can effectively realize the communication between the product terminal customers and the product production enterprises or departments, and reduce the communication difficulties or differences in the communication.

Waterproof Enclosures/ Housing/ Box Design

Waterproof Enclosures/ Housing/ Box Design

JH-C provides customers with professional waterproof box/shell Design. Before designing water-resistant box and case, you need to figure out the use environment of the product. 

1. Indoor use may splash water on the surface

        2.Use it outdoors in the rain

3.Use in shallow or deep water environments for long periods of time

We need to determine waterproof level according to these application environments so as to achieve the purpose of use and also save cost. General waterproofing grade is between IP63 to IP68. It is divided into

        IP63:  there is no effect when water or rain water drops on the housing from 60 degrees corner;

IP64: there is not affect when liquid is splashed to the shell from any direction ;IP65: wash the housing or shell with water without any harm;image.png

IP66: it can be used inside the cabin environment;

IP67: it can be resistant to immerse in a short time (1 minute);

IP68: It can resist water when it is submerged under a certain water pressure for a long time, such as deep-water cable.

At right picture, a waterproof box is placed outdoor open air, which is equipped with electronic components, circuit boards, batteries, sensors, therefore, its waterproof protection rate needs to achieve IP67.

The bracket design for waterproof box

The waterproof box needs to be fixed on a circular column, we need to design an opening metal locking ring. The locking ring will be used to connect the waterproof case and the column. To make metal locking ring and waterproof box formed a solid connection, our design engineers did some professional design. They made some mutual matching groove design respectively in the waterproof box and the metal ring, and the metal nuts were built into the box body by nut embedded molding process. Therefore, the nuts and the box become one entity and won't not loose. Metal nut is not easy to slip teeth. After the connection between metal ring and case body is good, we can lock the metal ring on the box by screws, so that the screw can mainly withstand horizontal force, the matched groove structures can bear the vertical force. 

The internal structure design for waterproof box

The internal of the waterproof case needs installing battery, PCB, sensor. Therefore, we need to carry out internal structural design according to the actual size of these components. At the same time, we need to consider the installion position of sensor by our customer re quirements.

 Waterproof cover design

1. What is the fastening method between waterproof cover and box?

   Using screws and embedded metal nuts come true the tight connection.

2. Which type of waterproof structure will be chosen?

    First, we need to understand common waterproof design methods:

    Seam Allowance method, waterproof ring method, ultrasonic method, secondary injection method, sealed and insulated circuit waterpoof design method.

    When you design water resistant electronic products, you must make the water level of  electronic products clear. Structural design methods are vary with waterproof grades. For example: the secondary injection waterproof design method can achieve IP8, Seam Allowance waterproof design method can only reach IP4.

    We choose the combined waterproof design methods of Seam Allowance and waterproof ring. Thus the waterproof box can reach a higher waterproof level.
