High Temperature PCB Manufacturing Process

The major difference between the manufacturing procedure for standard PCBs and that of high temperature PCBs is in the lamination process. This process is more detailed in the latter. The reason is pretty clear – materials used in high temperature PCBs need more heat and pressure to bond.

Here’s a step by step guide to the manufacturing process:

Step 1: Material Selection

Choose specialized materials that can take on extreme temperatures. Common high temperature PCB materials include ceramic-filled laminates, PTFE, and polyimide.

Step 2: Design

To ensure that the board withstands high temperatures, the design process is imperative. Appropriate materials, trace widths, and spacing is important when creating the design. Also, adding thermal management features such as vias and heat sinks can help to boost performance.

Step 3: Fabrication

Fabrication may include solder mask application, drilling, plating, and silkscreen printing. There are a few differences between this process in standard PCBs and in high temperature PCBs.

Step 4: Lamination

The lamination process bonds the different layers of material through stacking and applying heat and pressure.

Step 5: Testing

A series of tests ensures that the PCB meets set standards and specifications. Resistance, electrical continuity, and insulation resistance are tested. Thermal cycling is also conducted to check the board’s ability to take on drastic temperature shifts.

Step 6: Assembly

Assembly with relevant components follows. The assembly procedure is mostly carried out via automated assembly equipment.


High Temperature PCB FAQ

A high temperature circuit board is generally defined as an instance where the glass transition temperature (or Tg) is greater than 170°C. The glass transition temperature is one of the most important properties of any epoxy, representing the temperature where the polymer transition from a hard material to a soft one. High temperature PCBs should aim for a continuous thermal load around 25°C below the Tg.

FR-4 high Tg PCBs contain PCB material for high-temperature situations so you can count on them even under extreme temperature conditions. Typical PCB materials for high temperature may include NP-175TL, ITEQ-IT-180A, ISOLA 370HR, Shengyi S1000-2, and many others.

High temperature PCB - the best choice for your high-heat applications

A high temperature PCB is a circuit board that works perfectly in high-temperature environments. They are applied in sectors involving high heat, such as industries, in the automotive sector, and in the aerospace sector. The materials that make up a high temperature PCB can overcome high temperatures. Standard PCB materials cannot achieve this feat. 

The base material for high temperature printed circuit boards is comprised of polyimide or ceramic instead of the fiberglass epoxy found in standard PCBs. Using such materials ensures that the structural integrity of high temperature PCBs is maintained. It also ensures electrical performance in high temperature environments as high as 200 degrees Celsius. 

Aside from the base material, high temperature PCBs utilize specialized components including, thermal vias and high-temperature solders. This improves their thermal resistance capabilities. 

Thermal vias are holes that emerge from the surface of the PCB to the innermost copper layers. They help in heat dissipation from high-power components such as voltage regulators and power amplifiers. The heat goes to the other side of the board where it can escape freely.

What are High Temperature PCB Materials?

High temperature PCB materials are special substrates that can withstand elevated temperatures, mostly over 150 degrees Celsius. A high temperature PCB is preferred where ordinary PCB materials, such as FR-4, cannot tackle the environment. Here are some of the top high temperature PCB materials:

High Temperature PCB Materials

  • Polyimide – this is a high-performing polymer that can tackle temperatures of up to 400 degrees Celsius. It is applied in military and aerospace industries.
  • Polytetrafluoroethylene – otherwise shortened to PTFE, this is a thermoplastic material with ideal electrical and thermal properties.
  • Ceramic – many materials make up ceramic substrates including, beryllium oxide, aluminum nitride, and alumina. These materials can take up high temperatures of up to 1000 degrees Celsius. They are mostly ideal for high-frequency and high-power applications.
  • Liquid crystal polymer – this is a thermoplastic material with amazing dimensional stability and can withstand high temperatures.
  • FR-4 High Tg – this is a higher temperature version of the typical PCB material, FR-4. It can take on temperatures of up to 170 degrees Celsius and has excellent thermal stability.

What is High Temperature PCB Substrate?

This is the material used as the base layer for printed circuit boards. It should easily tackle elevated temperatures without distorting its form or compensating for its electrical properties.

Substrate material is the foundation of a PCB. It offers electrical insulation between different layers of the circuit.

High temperature PCB substrates emanate from materials with high temperature resistance. Aside from their incredible thermal stability, these materials also maintain their electrical properties at high temperatures. 

It is imperative to remember that the substrate alone isn’t enough reason for a PCB to withstand high temperatures. The design of the PCB also matters. When you increase the thickness of the copper traces, for instance, you can dissipate heat easily. The same applies to including extra insulation layers. These two measures can cut damage to the PCB by a great margin.

What are the Features of High Temperature PCBs?

High temperature PCBs are used where high thermal stability is supreme. To withstand such elevated temperature environments, they have the following features:

  • Advanced manufacturing solutions – to manufacture high temperature PCBs, you need advanced manufacturing solutions such as sequential lamination, laser drilling, and controlled impedance. This ensures high reliability and precision.
  • Resistance to chemicals and moisture – because of their resistance to moisture and chemicals, high temperature printed circuit boards can undergo harsh environments.
  • Specialized materials – high temperature PCBs are made up of materials with superb mechanical properties and high thermal stability. These materials can overcome elevated temperatures and harsh environments.
  • High melting point – materials used in high temperature PCBs have an extra high melting point. They can’t easily melt or degrade, even at high temperatures.
  • Low coefficient of thermal expansion – high temperature PCBs have a low coefficient of thermal expansion. This simply implies that their expansion and contraction doesn’t damage the board nor the components mounted on it.
  • Thermal conductivity – their high thermal conductivity enables high temperature PCBs to reduce the risk of thermal damage and to dissipate heat more effectively.
  • High glass transition temperature – it is mostly above 150 degrees Celsius, which implies that they don’t lose their electrical and mechanical properties when exposed to high temperatures.
