PCB milling has advantages for PCB prototyping and some special PCB designs. And the fact that there is no need to make the boards with chemicals is probably the biggest advantage. On the one hand, it takes time to outsource the creation of prototypes. The other is to do the circuit boards in-house. However, there are some problems with wet handling and handling chemicals in in-house production using chemicals.

In this article, we can will provide you with all the data information on multilayer pcb fabrication equipment. If you want to learn students some more about PCB equipment and functions, please check out and read on below.

What equipment is used in the production of multilayer printed circuit boards?

Solder Paste Printer

The first important piece of assembly equipment is the solder paste printer. This machine locks the PCB in an automatic solder paste printer. Then,PCB factory a rubber pad coated with the right amount of solder paste is used.

Next, a blade is dragged across the stencil to spread the solder paste evenly in the holes so that we only China later develops a layer of glue through the area of contact. After the mold by the state machine can be removed.

If all goes well, the paste should now be where the component will be placed later.

Solder Paste Inspection (SPI) Machine

SMD soldering problems are usually traced back to cheap solder paste printing. Any error in this step can mean that the component as a whole is not as reliable or robust as it should be.

Therefore, the next step is to use an SPI machine to check that the solder paste is printed correctly on the board.

The SPI machine uses a camera to capture a 3D image and evaluate the solder paste by solder volume, alignment and height. It also recognizes improper sizes and defects so the manufacturer can correct them.

Pick and Place Machine

This machine performs picking parts and placing them can on the board. This is probably the most obvious step in the management of the assembly work process and the most developmentally productive in China. Traditionally, this stage was done painstakingly by hand using tweezers.

But thanks to technological advances, manufacturers have now automated this step. The machine sucks up surface mount components and places them exactly on top of the solder paste in a pre-programmed position.

They are placed at high speeds and can place up to 30,000 parts per hour.

In printed circuit board assembly, surface mount or surface mount technology assembly using reflow soldering methods has four main stages: placement, automated component placement, soldering, and inspection (and testing, if required.) The basic equipment for PCB assembly includes.

-Solder Paste Printers

Solder Paste Inspection (SPI) machines

-Dispensers

Pick-and-place machines

Reflow soldering machine

Wave soldering machine (through-hole assembly)

-Automatic Optical System Inspection (AOI) Machine

‧Inline Test (ICT-RRB-fixture)

Functional Verification Test (FVT) fixtures

What is the importance of PCB equipment?

The manufacturing of medical devices is a tightly controlled process to ensure that the products produced are of the highest quality. In order to achieve this goal, manufacturers must keep the following objectives in mind.

-Product development must work in all environments, so we must have designs that are more robust than the standards carried out for consumer finance products.

-Products must operate safely under the intended conditions. Medical devices can be used in a variety of environments and the user needs to be able to operate the device without fear of shock or failure.

Products must be designed in accordance with applicable industry standards, such as ISO 13485. in addition, the standards define traceability requirements so that when a problem is reported with a particular component, you can quickly find out which component was used in which device.

The product must be manufactured by a manufacturer that holds a valid medical device manufacturing license, such as the State of California's Medical Device Manufacturing License.
