Photoresist is a material that semiconductor suppliers are constantly working with. This light-sensitive material is divided into two types: negative and positive, which react in very different ways when exposed to UV light . It is therefore essential to understand each reaction in order to produce the best results in the semiconductor manufacturing industry. Positive Photoresist : UV light is used to expose the resist where the fundamental material is to be detached. Contact with UV light changes the chemical structure of these resists, making them more soluble in the developer. The developer solution then washes away the exposed resist, separating the windows from the base material. The mask thus covers an accurate copy of the shape that will be left on the wafer as a stencil for further processing. Negative Photoresist : A negative photoresist works in the opposite direction. When the negative resist is exposed to UV light, it polymerises and becomes more difficult to dissol...

Every manufacturing plant has to go through the tedious task of contracting with reliable suppliers, especially when it comes to chemical allocation. Purchasing chemicals is therefore a crucial task for manufacturing companies, as they need to use pure and exact compositions of chemicals to produce a quality product. However, finding pure chemicals can be a difficult process, as can finding their supplier. With the number of fraudulent suppliers increasing in the chemical industry, chemical buyers can face serious risks in this process. It is therefore essential to check the authenticity of suppliers when purchasing chemicals. So how do you identify a genuine supplier who can provide you with the quality and quantity of chemicals you need while offering a market standard price? Here are some factors to check: Supplier's reputation The first thing you should consider before diving into the search for a chemical supplier is their reputation, experience level and customer service....

Photoresist printed circuit boards are essential for the manufacture of electrical devices. Photoresist is also a key component of the PCB. Everything you need to know about photoresist PCBs is explained in this article. The traces on a board are made by electroplating and etching techniques by large-scale PCB manufacturers. The electroplating production procedure begins with the application of electroplated copper to the substrate of an outer layer board. Another crucial step in the creation of printed circuit boards is the Photo-Resist dryfilm etch. It is important to strike a balance between removing unwanted copper and keeping the resist in place to protect the desired copper during the etching process. For the latest product selection guide please click here What is a photoresist PCB? A photoresist PCB is a high quality PCB, perfect for many applications. This type of PCB is ideal for producing double-sided PCBs. For photoresist PCBs, only high quality materials are used....

Without a printed circuit board, an electronic assembly cannot function properly. A printed circuit board or PCB ensures that electronic devices have proper mechanical support. Depending on the application, you need to choose the right PCB. Some of the most commonly used PCBs are rigid, rigid-flex, aluminium core and flexible. Before choosing a PCB supplier, you need to determine whether or not they can provide you with the right product. Here are 5 tips for choosing the right PCB supplier inthe UK : Requirements Before hiring a PCB supplier, you must be sure about the PCB type you need. To be able to determine that, you need to have complete clarity about the purpose you plan to use it for. Location, type of material, certification and processing abilities are some of the things you need to keep in mind. Expertise The PCB supplier you choose should have relevant industry experience. Apart from that, they should have a good knowledge of printed circuit boards. There are vario...

Devices such as smartphones, smart watches, gaming consoles etc. are classic examples of how technology has evolved and the power these devices hold comes from the microchips which are small but extremely powerful pieces of technology which are manufactured through a process which is not simple. Here we will explain the 5 crucial steps involved in semiconductor manufacturing: Deposition: The process starts with a silicon wafer. Wafers are cut from an ingot (bar with 99.99% silicon) and are polished until they are smooth. Thin films of isolating, semiconducting or conducting materials are then deposited on the wafer so that the first layer gets printed on it. This process is called deposition. Photoresist coating: After the deposition phase, the wafer is covered with either a positive or negative light sensitive coating which is called resist or photoresist. In the positive resist, the areas that are exposed to ultraviolet light change their structure and are made more soluble for dep...
