Today author from QiHe smt pick and place machine smt equipment manufacturers sharing you with Problems that are prone to occur in the process of PCB plate making
When we design on PCB design software,
Often due to the seemingly connected parts (electrical performance) on the plane but actually not connected,
So when we start plate making according to the design document,
Order of operations is very important.
Today we go through the following three tricks,
Focus on solving the problems that are prone to occur in the process of PCB plate making.
A making a physical frame
Making a closed physical frame on the original board is a constraint effect on the layout and wiring of later components.
After a reasonable physical frame setting,
The soldering of components one by one and the accuracy of wiring can be more standardized.
But pay special attention to,
Some boards or corners with curved edges,
The physical border should also be set in an arc shape,
The first precaution is to prevent sharp corners from scratching workers,
The second stress relief effect ensures safety during transport.
B. Introduction of components and networks
It should be easy to draw components and nets into the drawn border,
But there is often a problem here,
Be sure to carefully solve the errors one by one according to the prompts,
Otherwise, it will take more effort later on.
The problems here are generally the following:
The packaging method of the component cannot be found,
component network issues,
There are unused components or pins,
Control hints that these problems can be solved quickly.
C． Layout normalization of components
(1) Placement order
Experienced installers will first place components with a fixed orientation related to the structure,
Such as power sockets, indicator lights, switches, connectors and the like.
Then it is locked by software,
Make sure that the components with fixed orientation are moved or affected when other components are placed later.
We can divide according to the placement order,
Do it several times.
(2) Pay attention to the influence of layout on heat dissipation
Component layout should also pay special attention to heat dissipation.
Regarding high-power circuits,
Those heating elements such as power tubes and transformers should be placed as far as possible in a scattered layout.
for heat release,
Don’t concentrate in one place,
Also don’t put the high capacitance too close to avoid premature aging of the electrolyte.
Through the above three points, I hope to help the engineers of PCB production.

What is SMT used for?
Surface mount technology is a part of the electronic assembly that deals with the mounting of electronic components to the surface of a PCB. Electronic components mounted this way are called surface-mounted devices (SMD). SMT was developed to minimize manufacturing costs while making efficient use of board space.Qihe SMT company develops and produces all kinds of SMT equipment suitable for world wide market, including pnp machine,reflow oven,stencil printer,pcb handling machines,and other products.

WHAT IS SMT pick and place machine？
SMT (Surface Mounted Technology) is a comprehensive system engineering technology, which covers substrates, design, equipment, components, assembly processes, production accessories and management. When it comes to SMT pick and place machines, the automatic SMT production line requires automatic loading and unloading machine, automatic solder paste printing machine, placement machine, reflow soldering machine, AOI inspection equipment, connecting table, etc. For these SMT assembly line equipment, Qihe SMT can offer you machines in prototype SMT line, small SMT production line, mass production SMT line at low SMT line cost. Contact us now if you are interested.
WHAT IS SMT ASSEMBLY LINE？
With the development of technology, future electronic products will be lighter, smaller and thinner. Traditional assembly technology can no longer meet the requirements of high-precision and high-density assembly. A new type of PCB assembly technology-SMT (Surface Mount Technology) has emerged. SMT Assembly is the use of automated machines to assemble electronic components on the surface of the circuit board. Its density, high speed, standardization and other characteristics occupies an absolute advantage in the field of circuit assembly technology. In addition, SMT assembly has a wide range of uses.
WHAT IS SMT PROCESS？
There are mainly three steps in SMT assembly line process flow： solder paste printing, components placement and reflow soldering.
- Solder Paste Printing
Its function in SMT line process is to print the solder-free paste on the pads of the PCB to prepare for the soldering of the components. The equipment used is a screen printing machine, located at the forefront of the SMT production line.
- Components Placement
Its function is to accurately install the surface mount components on the fixed position of the PCB. The equipment used is a placement machine, located behind the screen printing machine in the SMT production line.
- Reflow Soldering
Its function in SMT manufacturing line is to melt the solder paste so that the surface mount components and the PCB board are firmly bonded together. The equipment used is a reflow oven, located behind the placement machine in the fully automatic SMT production line.
