Colorado pcb assembly has decades of experience in rapid prototyping and assembly and is one of the most professional and experienced PCB assembly service providers in the United States.They provide assembly services to many companies in many industries, covering telecommunications, LED lighting, automotive, medical, consumer electronics and many other fields.So, in China, iPCB is committed to providing personalized services to customers and strives to be unique in the industry. Our professional team also provides a large number of production and assembly for customers around the world.
The design team has more than 80 people, a large-scale high-speed PCB design team, nearby services, and convenient communication. The average industry experience of engineers is more than 8 years, and senior employees have 10-20 years: the industry's recognized PCB design talent base; pcba assembly provides parallel design, shortens delivery time, and can conventionally shorten PCB design time by more than 1/3.
And it has its own PCBA factory to ensure the DFM characteristics and cost control of PCB design, and self-developed tool software + quality control system to ensure the success of one board. Check Lists with hundreds of items including layout, wiring, high speed, thermal design, structure, etc. are the experience accumulation of all employees. Strict quality system and self-inspection mechanism. Strict mutual inspection system and perfect DFM inspection process. A group of senior experts participated in the review and comprehensively checked the principle design, DFM, DFT, high speed, EMC, thermal design, etc.
PCB assembly is the last step performed in the circuit board manufacturing process (the other step is manufacturing), which is defined as follows:
The PCB assembly process is carried out after the bare board is manufactured. It refers to the connection of the devices selected during the design and listed in the bill of materials to the PCB through the soldering process (wave soldering, selective soldering or reflow soldering), depending on the type and size of the device used.
The main purpose of PCB assembly is to connect THT and/or SMT devices. However, as the last step in the manufacturing process, the assembly process also requires inspection (such as automatic optical inspection), testing (such as flying probe or other online testing), cleaning, conformal coating or other protection, and panelization. Although in practice these tasks are performed by contract manufacturers, the decisions made by designers during the design process can greatly affect the quality of the built circuit board.
So let's first understand what SMT is?
1. Definition of SMT
Surface Mounting Technology (SMT) is a new generation of electronic assembly technology. It compresses traditional electronic components into devices with a volume of only a few tens of times smaller, thus achieving high density, high reliability, miniaturization, low cost, and automated production of electronic products. This miniaturized component is called SMD device (or SMC, chip device).
The process of assembling components onto printed circuit boards or other substrates is called SMT process. The related assembly equipment is called SMT equipment.
2. Characteristics of SMT
(1) High assembly density, small size and light weight of electronic products. The size and weight of SMT components are only about 1/10 of traditional plug-in components. Generally, after adopting SMT, the size of electronic products is reduced by 40% to 60%, and the weight is reduced by 60% to 80%.
(2) High reliability, strong shock resistance, and low solder joint defect rate.
(3) Good high-frequency characteristics, reducing electromagnetic and radio frequency interference.
(4) Easy to realize automation and improve production efficiency. Reduce costs by 30% to 50%. Save materials, energy, equipment, manpower, time, etc.
3. Why use SMT
(1) Electronic products pursue miniaturization, and the perforated plug-in components used in the past can no longer be reduced
(2) Electronic products have more complete functions, and the integrated circuits (ICs) used no longer have perforated components, especially large-scale, high-integration ICs, which have to use surface mount components
(3) Product mass production, production automation, manufacturers need to produce high-quality products at low cost and high output to meet customer needs and enhance market competitiveness
(4) The development of electronic components, the development of integrated circuits (ICs), and the diversified application of semiconductor materials. The electronic technology revolution is imperative and pursues international trends
4. SMT process
The SMT process is to use the machine's suction nozzle to pick up SMT parts, identify the parts through image processing, and then place them on the substrate with solder paste printed on it. The substrate is then heated in a reflow furnace to achieve the purpose of welding.
