Giant is a professional PCB assembly manufacturer in China, which can provide customers with SMT chip processing, fast chip proofing, PCB assembly processing, PCBA fast proofing and other services. The production workshop is full of imported SMT equipment and has many years of industry processing experience. The following Giant custom PCB assembly manufacturer will introduce the SMT placement process.
Giant custom PCB assembly manufacturer introduces the SMT placement process
What is SMT? SMT is a new generation of advanced electronic assembly technology. Simply put, it is a process of mounting components on the PCB panel and mounting the components on the PCB.
The machinery and equipment used in the Giant custom PCB assembly manufacturer SMT process are:
1. Fully automatic printing machine.
The function of the printer is to print the solder paste on the pads of the PCB. Since the circuit and pad points have been typeset on the PCB board, the printer will automatically identify the pad points on the PCB board. This is the forefront of SMT production.
2. Solder paste inspection machine.
It is used after the solder paste printer and before the placement machine. Use high-tech structured light measurement to measure the solder paste of printed PCB panels with micron-level precision. The advantage is to find the bad phenomenon of solder paste in time before soldering.
3. High-speed placement machine, also known as the placement machine.
After printing the solder paste, it is a fully automatic process in which the components are accurately and accurately mounted on the PCB panel by moving left and right.
4. Reflow furnace machine.
It is firm by remelting the solder paste distributed on the printed PCB pads to realize the soldering of the surface components or the firmness of the pins.
5. AOL optical inspection machine.
It is mainly to detect multiple parts, missing parts, wrong parts, reverse stickers, positive and negative electrodes, replacement parts, and whether the pins are bent, text recognition, and so on.
What are SMT's technological processes? The above probably understands the use of the machine and its basic function. In fact, the production process of SMT is completely compatible with the machine. The production process of Giant custom PCB assembly manufacturer SMT is:
1. Put solder paste on the prepared PCB panel first, and make the prerequisite steps for the placement of the components.
2. Dispensing is to drop the industrial glue onto the fixed position of the PCB panel, and its role is to fix the components on the PCB panel.
3. Mounting, accurately mount the components on the PCB panel.
4. Curing, so that the surface mount components and PCB board are firmly bonded together.
5. Reflow, melt the solder paste and pass the high temperature of the reflow furnace to make the solder paste melt firmly.
6. Cleaning to remove harmful residues on the PCB panel.
7. Detection, custom PCB assembly is completed by an SMT mounting process.
The above is the SMT placement process introduced by Giant custom PCB assembly manufacturer.
