Is Tg130 PCB Enough for your Design

When you first start as an electronics enthusiast, it becomes impossible to imagine how extensive the field can become. Each subject and subject you get to cover in electronics will have more information than the subsequent one. The same applies to printed circuit boards. At first, all that I thought about as an enthusiastic electronic design beginner entailed the need to understand circuit boards, the diverse types in existence, and the manufacture, assembly, and fabrication process. However, ten years and counting, and I still have to learn about specific PCB-related aspects.

This article will detail every crucial detail you have to learn concerning the standard or low tg130 board thickness. Similar to my previous situation, I am sure that reading this piece will prove enlightening, especially in tg130 PCB and other related standard-size printed circuit boards. Let us now get right into it, shall we?

TG130 Printed Circuit Boards

TG often refers to the glass transition temperature, which every printed circuit board possesses to varying degrees. For instance, a standard fr4 tg130 board possess a glass transition temperature value of 130 degree Celsius. The abbreviation term “TG” gets defined as the temperature range upon which the base material of a circuit board becomes unstable (mechanically).

Therefore, a glass transition temperature (Tg) becomes the value of temperature that ascertains a printed circuit board’s mechanical stability, especially in its operational shelf-life. Circuit boards often entail paper or glasslike substances reinforced by resin epoxy to give it its non-conductive and structural platform. In most cases, such material gets referred to as an fr4. A PCB’s fr4 always proves fire-retardant, implying that it cannot get melted or burned by flames or high temperatures. However, this material often changes its form into an amorphous and rubbery state when subjected to higher than conditioned temperatures or Tg values.

An rf4 tg130 board will consist of numerous glass fiber epoxy laminate layers and have a Tg-value of 130 degrees Celsius. While most manufacturers consider the tg130 as the basic low-Tg standard for printed circuit boards, you can always find PCBs with higher TGs falling under the mid-Tg range above 130 degrees Celsius and below the 170 degree Celsius mark. Additionally, there exists the high-glass transition temperature range that starts from 170 degrees Celsius or higher.

Different glass transition temperature value PCBs have different applications with higher TGs proving more suitable to higher operating or manufacturing temperature conditions. However, please note that the TG value should not imply the actual operating temperature of the board. It would help if you always aimed to operate the printed circuit board at about 25 degrees Celsius less of the TG value.

So do you want to procure a standard tg130 printed circuit board but have no idea what to consider or how to go about it? It would help if you considered the details provided below.

Crucial Information on the Standard TG130 PCB

  • Laminate requirements. It often depends on the thickness of the PCB board desired. The tg130 PCB can come with a board thickness of less than 0.5mm or equal to or above 0.5mm. You have an option of choosing what board thickness you want based on other influencing factors and the purpose of the tg130 printed circuit board.
  • Minimum peel strength. The classification includes three broad categories: the standard profile copper foil, the low profile copper foil, and every other foil composite. All three classes possess different values and specifications based on the thickness range. Additionally, the low-profile copper foil can have different values based on the temperature state. For instance, at 125 degrees Celsius, after the process solution, and after the thermal stress.
  • Minimum volume resistivity. Segmented into three categories, the standard tg130 PCB can prove C-96/35/90, post humidity conditioning, and higher temperature E-24/125. All category values and specifications depend on the thickness of the board.
  • Minimum surface resistivity. Three categories of the tg130 PCB exist. It includes the C-96/35/90, post humidity conditioning, and at higher temperature E-24/125. The diverse classes or categories all show diversity concerning board thickness.
  • Maximum moisture absorption with different typical values based on the thickness differences
  • Permittivity and the minimum arc resistance also apply though they differ with the board thickness.
  • Minimum flexural strength comes under two groups of cross and length directions, and these also differ in value and specification depending on the thickness of the tg130 board, especially on the more than 0.5mm thickness.
  • Minimum thermal stress can either as etched or un-etched, with all the tg130 board thickness values passing.
  • Minimum electric strength also differs with the thickness of the board sizes, with thicker board sizes having less strength compared to thinner tg130 PCBs.

Factors that Influence the Price of a Tg130 PCB


Printed circuit boards, in general, have attributes that can increase or decrease the cost of the PCB. The tg130 PCB proves similar, and its price will get influenced by the following. However, before we get to the price determinants, it becomes essential to note that a tg130 comes as the standard board type. The pricing will prove more affordable compared to higher TG printed circuit boards.  

  • Choice of material. The type of material used will always impact the total cost of a printed circuit board. Materials involved in a tg130 PCB entail the glass-resin epoxy material, the copper layer, and other crucial components. However, the substrate (composed of the fr4) proves the most significant price determinant. The tg130 contains this rf4 material, which costs less than other higher glass transition temperature lamination substrates (like the rf4 tg150, rf4 tg170, etc.). A case in point is the tg150 which costs 5% higher than a tg130 PCB.

Please note that a PCB requiring higher frequencies or speed will need a higher and better grade than the typical fr4 substrate. You may need to use a polyimide material that increases the price by about three times in such a case.

  • The tg130 printed circuit board size will also determine the price directly. It arises because more space implies the need for more materials and more work, which inflates the price. You, therefore, have to consider this aspect when designing your tg130 PCB.
  • Utilization of the working panel. Your PCB will cost less if, in your tg130 design, you have ensured maximum working panel utilization. The percentage of work panel utilization comes as a factor of an array or single unit area and the total quantity within the working layer/panel, all divided by the working panel area, with the result multiplied by one hundred. Therefore, learn to utilize the panel space better to keep your PCB manufacturing costs lower.
  • Via design
  • The design of via deployed in your tg130 PCB will determine the manufacturing cost and thus the price. For instance, when you decide to opt for a via-in-pad design, it will need the plugging of via with resin first before the copper plating process, which will drive up the manufacturing costs. It arises because the drill type for this via design will differ from one via design to the other. For instance, a 0.15mm drill bit can prove expensive besides having the knack of getting broken easily. You, therefore, cannot use this drill type for drilling vias in thicker circuit boards. You, therefore, have to consider this before selecting a manufacturing company and accompanying cost implications in the final PCB prize.
  • The design of the high-density holes will also impact the cost of manufacturing, as it will require more precision and work compared to less-dense holes in the printed circuit board.
  • Tight tolerance. It also influences the price of a standard PCB, especially when excessively tight. Hole sizes need to have a +/- 0.05mm tolerance, with a tighter impedance above +/-10%. Consequently, this provides an aspect ratio of 8:1. It should also possess a gap and track of less than 4mil/4mil, with tighter outline dimensions of +/- 0.10mm.
  • Lead time. The price of tg130 PCB will depend a lot on the lead time specified. For instance, when you do not provide a timeline for the manufacturer to deliver your PCB, they can work faster, which comes relatively affordable. However, with strict and short timelines, the cost of the PCB will become steeper. The price increase gets accounted for by the contracted manufacturer putting everything else on hold to work on your printed circuit board and deliver within the timelines provided. Consequently, it leads to compensates for the lost opportunity to make money from other similar projects during your work.
