SMT makineleri, also known as Surface Mount Technology machines, refer to a broader category of machines in the Yüzey Montaj Teknolojisi process including equipment for placing components, applying solder paste, yeniden akış lehimleme, and inspection systems. Aslında, these machines allow us to position surface mount components, dirençler gibi, kapasitörler, integrated circuits and LEDs, rapidly and accurately at certain locations on a PCB. SMT machines can place as little as 0.4 x 0.2mm, and they can place hundreds or even thousands of parts per hour. They aid in the increase in the manufacturing production speed and accuracy and are used widely around the world.
Sırasına göre SMT PCB montajı işlem, we will list the equipment used one by one:
In SMT process, this machine exactly apply the solder paste on the PCB pads. Bu nasıl çalışır: In using a stencil and squeegee system to distribute the paste evenly, they are able to make sure the components will be mounted correctly in subsequent stages.
After applying paste, this crucial machine then uses advanced 3D imaging to inspect the solder paste. It grades volume, alignment and height while identifying any defects that could cause soldering problems.
This kind of machines are available in three types:
After component placement, this oven then cures the solder paste and secures components to the PCB.
This critical equipment is used to preheat components and melt the solder paste which in turn form permanent connection between the SMDs to the PCB. The design is meant to enable solid joints without damaging sensitive parts.
This machine removes any residual flux and excess solder from PCB to give a clean surface for best performance.
The last stage which comes in at a sophisticated machinery that checks assembled PCB for any defect. Ek olarak, it assists in fixing these issues to ensure the quality.
Pick and place machine plays a critical role of the overall SMT line, we list the best 8 SMT pick and place machines and explain their features one by one as followed:

Montaj hattınız için uygun bir SMT makinesi seçmek kolay bir iş değildir, karar vermeden önce göz önünde bulundurmanız gereken birkaç faktör var:
The focus of the initial research on the purchase of SMT placement machine is on the placement speed. There exist different placement machines, at different placement speed and it is essential to select one that fits within your production needs and your budget. They can be checked against the IPC 9850 standart, which states the desired speed of their pick and place machines.
Another important aspect is placement accuracy. With more accurate machines, yields are higher and they can perform better. To get the best accuracy you need an optimal SMT machine with an accuracy of 0.0001″ and a fine pitch lead of 12mil.
Elbette, picking an SMT machine is not only about how accurate it will be, but also if it will consistently produce the same results. Repeatability is another factor you should consider, especially with machines that run on programmed software solutions.
Dikkate alınması gereken bir diğer önemli faktör parça boyutudur.. Örneğin, bir alma ve yerleştirme makinesi, boyutların parçalarını işleyebilmelidir 0402, 0201, ve 01005. If your other requirements for your machine are being met, but the machine does not support these sizes, you can buy a nozzle (or a feeder) which will make it possible to produce circuit boards of these sizes.
This blog should give you some idea about what SMT equipment you need if you want assemble electronic boards, and suggestions on which brands you can purchase the SMT pick and place machines. ancak, it might not be the most efficient approach to pay for purchasing these expensive machines if you are making only a few boards. Bu tür durumlarda, partnering with a responsible PCB manufacturer is a better alternative as they could supply faster and more reliable services. Equipped with the best industrial equipment, MOKO Technology can provide the one stop PCB assembly services including PCB manufacturing and PCB assembly and inspection for customers.
