The Basic Components and Structure of a Thick Film Heater
A typical Thick Film Heater consists of several components or layers. The selections of dielectrics, conductor, and resistive ink, as well as the determination of their combinations are dictated by the properties of these materials and thermal-electrical requirements of the end TFH products, also by the application or process compatibility with the operating temperature and cycle rates, watt density, and environment.

Thick Film Heating: Introduction
When considering a surface heating solution for your project or process, how about a heater that can be described as lighter, thinner, smaller, and faster? Well, if this is music to your application designers or project engineers, Heatron has made it possible by providing a wide range of highly customizable Thick Film Heaters (TFH) that are ideal for heating applications and can be the game changer to solve the problem!Heatron offers four major categories of a variety of unique TFH products: Ceramic Core Alumina (Al2O3), Ceramic Core Aluminum Nitride (AlN), Thick Film Aluminum (Al), and Thick Film Stainless Steel. Each of these can be customized to suit projects in the industries, such as Medical & Life Sciences, Aviation and Transportation, Security, Food Service, Printing, Industrial, and Semiconductor Industry, to just name a few.Thick Film Heaters are built using a deposition process by screen printing resistive or conductor traces on top of a substrate. The deposition process allows for close control of the thickness and width of the resistor, thus, accurately controlling the heater’s resistance, wattage, watt density, and uniformity of the heated part.The nomenclature for a Thick Film Heater is determined by the substrate used. For example, “Ceramic Thick Film Heater” has its name from ceramic being used as the substrate. Heatron’s ceramic TFHs are Ceramic Core Alumina (Al2O3) and Ceramic Core Aluminum Nitride (AlN), in addition to Thick Film Aluminum (Al), and Thick Film Stainless Steel that are made with substrates of Aluminum and Stainless Steel, respectively.

Application Spotlight: BEV and FCEV
Electric Vehicles come in many flavors, but the most popular are Battery Electric Vehicles (BEV) and Fuel Cell Electric Vehicles (FCEV). These descriptors refer to how the energy is stored in the vehicle. The vehicle can be anything from a scooter to a drone to a car to an airplane. The common characteristic is that electricity powers and propels the vehicle.However you store the energy and regardless of the use case of the vehicle; there will be a need for heating elements.
Application Spotlight: PCR Testing
PCR (Polymerase Chain Reaction) testing is a phrase you may have come across often in 2020. Most of us have never heard it before. What is it?The good people at genome.gov refer to this process as “molecular photocopying” in laymen terms. The general idea is to create more DNA samples from a small amount of DNA samples in order to make detectable all the DNA present in a given sample.It has gained prominence in our daily lives thanks to COVID-19. This process is considered to be the gold standard by which the most accurate COVID-19 test results are achieved. This style test looks for the virus, sars-cov-2, itself.This test is supplemented by other testing such as antigen and antibody testing. Those tests utilize a different process as they are blood tests that are searching our blood for evidence of immune system reaction to the virus.The process of PCR testing is complicated. I would try to paraphrase, but it is better that I provide the exact quote from genome.gov.“To amplify a segment of DNA using PCR, the sample is first heated, so the DNA denatures, or separates into two pieces of single-stranded DNA. Next, an enzyme called ‘Taq polymerase’ synthesizes - builds - two new strands of DNA, using the original strands as templates. This process results in the duplication of the original DNA, with each of the new molecules containing one old and one new strand of DNA. Then each of these strands can be used to create two new copies, and so on, and so on. The cycle of denaturing and synthesizing new DNA is repeated as many as 30 or 40 times, leading to more than one billion exact copies of the original DNA segment.The entire cycling process of PCR is automated and can be completed in just a few hours. It is directed by a machine called a thermocycler, which is programmed to alter the temperature of the reaction every few minutes to allow DNA denaturing and synthesis.”There are many ways different medical equipment OEMs try to automate the process. Heatron has been working with OEMs manufacturing heating elements to their PCR test equipment standards for 20 years. At the time of publishing this post, Heatron is making heating elements for many different OEMs that make PCR testing devices. These OEMs are a mix of established, perhaps even household, names as well as those in the start-up stage. The equipment itself varies from high volume, lab equipment to attempts at point of care (the doctor’s office or hospital) devices. The heating elements supplied are as varied as can be. No two OEMs we work with are developing anything that can be reasonably viewed as same heating platform.Manufacturing for medical OEMs requires a certain level of diligence, process control, quality standards and traceability. Heatron excels at all of these and the long track record is the testimony. Heatron is a trusted collaboration partner for medical OEMs. Heatron is capable of manufacturing discrete elements as well as complex assemblies.Contact us today for help with your project!
