Prototype PCB Rigid Printed Circuit Boards


4mil Prototype Circuit Board Assembly

Through Hole OSP Gold Finger Quick PCB Prototype Service Fabrication FR-4


Panel, as the name implies, is to assemble one or several single-board PCB prototype into the same Panel.


The purpose of the panel:


The original veneer is too small, and it is not easy to pick up after the PCB prototype  is formed or after the PCBA.

After the panels are assembled, the cost of the test fixture and the test man-hours can be saved, and the efficiency can be improved.

The single board is too small or there is no optical point (Fiducial mark) in the single board, but the PCB prototype  has SMT requirements.

There is no hole in the veneer board to fix the PIN for CNC molding, so it is necessary to add a break-away, drill a PIN hole and place an optical point (Fiducial mark).

For the efficiency of SMT printing. At the current speed of the placement machine, the PCB prototype passes through the placement machine once, and the number of seconds spent on each board will not be too different. Therefore, the utilization of the appropriate single board to form a Panel is relatively high.

Increase the board edge (Break-away) for track conveying during PCBA production.

Special PCB Prototype Type

FPC (Flexible Printed Circuit)

The flexible board is made of a soft plastic base film, copper foil and adhesive, which can be freely bent and flexible. It is thin and light, with high precision. It can have multi-layer circuits and attach chips to the board. or SMT wafers. It is generally called a flexible printed circuit board, abbreviated as a flexible board, and other names such as flexible circuit boards, soft films, flex boards, etc.
Like other substrates, FPCs continue to pursue higher line density and number of layers to improve FPC performance and reduce transmission power consumption. However, the manufacturing process of FPCs is very complex, and the technical capabilities required in electronic components are relatively high. 

The application of FPC is very extensive. It can be said that as long as it is used in technological products, FPC is most commonly used in communication products such as smart phones. In addition, there are notebooks, automotive electronics, medical, military and wearable devices, etc. As modern products pursue light, thin and short, flexible boards have also become very important. According to statistics, the number of FPCs used in the iPhone X accounts for about 20 pieces. In addition to the iPhone, these FPCs play the following roles in terminal equipment: antenna FPCs, backlight module FPCs, camera lens FPCs, Touch screen soft board, Touch ID soft board, sim card soft board, laptop screen connection soft board, car image sensor soft board, car light group soft board, etc., we can see the importance of soft board.

Flexible boards are divided into PI, MPI, and LCP by material. MPI is the modified PI. PI is almost eliminated because of its poor performance. Now the main materials used for flexible boards are MPI and LCP, and the performance of LCP is higher than that of MPI. , The relative price has also increased significantly. In terms of cost performance, it is generally believed that MPI is relatively high, especially in recent years, the performance of MPI has been greatly improved, and it has further threatened LCP. As in 2018, Apple also decided to replace some LCP soft boards with MPI soft boards. reduce costs. The biggest consideration factor in the use of the three types of flexible boards is the transmission loss. In the case of low frequency transmission, the loss of the three is not significantly different. However, as the frequency increases, the loss of PI gradually increases, and the loss of MPI and LCP also has a greater difference. , so in the case of higher frequency, the advantages of LCP will be more obvious. It can be seen that in the 5G era, some of our transmission frequencies will be greatly increased to above 24GHz, and there will be higher requirements for the quality of the soft board. 



PCB Prototype surface treatment

Since the copper surface of the PCB Prototype Service is easily oxidized in the environment, it must be reprocessed and covered with a layer of coating on the exposed area that is not covered with solder mask ink to protect the process from oxidation. In response to various subsequent processing needs, various surface treatment processing methods with different materials, prices and different degrees of protection have been developed.

Common PCB Prototype Service surface treatments include the following:

Bare copper plate, spray tin plate, lead-free spray tin plate, chemical gold plate, electroplating gold, chemical silver plate, OSP plate.
