High TG PCB assembly and manufacturing in Brazil

As an important industrial country in South America, Brazil has made significant progress in high TG PCB assembly and manufacturing in recent years. This article will introduce in detail the relevant situation of high TG PCB assembly and manufacturing in Brazil, including process flow, material selection, quality inspection, etc.

High TG PCB assembly and manufacturing process in Brazil

The manufacturing process of high TG PCB mainly includes the following steps:

  1. Plate preparation: Select appropriate high TG plates, cut and clean them. High TG sheets have a higher glass transition temperature and excellent heat resistance, and can withstand higher processing temperatures and ambient temperatures.
  2. Circuit production: Circuit production is carried out on the board according to the circuit design. This step can use different process methods, such as engraving, photolithography, etc. After the production is completed, the circuit needs to be inspected to ensure that it meets the design requirements.
  3. Mounting components: Mount electronic components onto the PCB board. This step requires the use of a precision placement machine to ensure accurate component positioning and reliable welding. At the same time, strict quality control of the mounting process is required to prevent problems such as false soldering and wrong soldering.
  4. Wave soldering: Wave soldering is performed on the assembled PCB board to realize the electrical connection between the components and the PCB board. During the wave soldering process, welding temperature, time and solder quality need to be controlled to ensure welding quality.
  5. Quality inspection: Conduct quality inspection on the welded PCB board, including electrical performance testing, appearance inspection, etc. Unqualified PCB boards need to be reworked or scrapped.
  6. Packaging and storage: Pack the qualified PCB boards and store them in the warehouse. Packaging materials should have good moisture-proof and shock-proof properties to ensure that the PCB board is not damaged during transportation and storage.

High TG PCB material selection

In the manufacturing process of high TG PCB, it is necessary to select suitable high TG plate materials, solder and mounting components. The quality and performance of these materials directly affect the heat resistance, electrical performance and reliability of high TG PCB. When choosing materials, you need to consider the following aspects:

  1. High TG sheets: Choose sheets with high glass transition temperature and high heat resistance, which can withstand higher processing temperatures and ambient temperatures. At the same time, the dimensional stability, mechanical properties and electrical properties of the board need to be considered.
  2. Solder: Choose solder with excellent wettability and conductivity to ensure the quality of wave soldering. At the same time, factors such as the melting point, composition and cost of the solder need to be considered.
  3. Mounting components: Choose mounting components suitable for high TG PCBs, such as high-temperature stable electronic components and metal film resistors. These components need to maintain good performance and reliability in high-temperature environments.

Quality Inspection

The quality inspection of high TG PCB is an important part of the manufacturing process, including visual inspection, electrical performance testing and reliability testing.

The appearance inspection mainly checks the flatness, solder joint quality, circuit integrity and component mounting of the PCB board; the electrical performance test mainly tests the resistance, capacitance, inductance and other electrical parameters of the PCB board; the reliability test includes thermal cycle testing, High temperature storage testing and life prediction, etc., to evaluate the stability and reliability of high TG PCB in actual use environment.

Unqualified PCB boards need to be reworked or scrapped to ensure the quality and reliability of the final product.

Summarize

High TG PCB assembly and manufacturing in Brazil requires strict quality control and meticulous process management. By selecting appropriate high TG materials, adopting advanced manufacturing processes and conducting strict quality testing, high-quality high TG PCB products can be produced to meet the needs of different fields.

With the continuous advancement of technology and the growing market demand, Brazil’s high TG PCB assembly and manufacturing industry will usher in broader development opportunities.
