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.

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...

Seen a solder mask on the PCB? Well, you must have seen it a couple of times without realising that it is a solder mask that you are looking at. The top green colour layer on the PCB is the solder mask which helps in preventing visual fatigue while assembling, providing considerable aid during the inspection and delivers protective cover for the conductors. To protect the metal elements on the circuit board from oxidation, a solder mask or solder stop mask is one of the crucial steps in the PCB process. The solder mask is also called solder resist since it gives you some amount of control over where the solder bits will land on the board. While selecting the correct solder mask for your PCB you need to consider your assembly process. Thus, the different categories of solder masks are: Liquid epoxy solder mask: This is the most cost-effective and easy solder mask option available in which a woven mesh is used to provide the support needed for ink-blocking patterns. The thermosetting p...

The phosphating process is implemented for converting a steel surface into iron phosphate, which is a pretreatment method merged with another method for corrosion protection. The phosphate coating generally involves iron, zinc, or manganese crystals. Phosphating is typically applied to cast iron, carbon steel, and low-alloy steel. This coating is mainly prepared with a solution of iron, manganese, or zinc phosphate salts in phosphoric acid. Then it is applied by either dipping the substrate into the solution or by spraying it onto the substrate. As the iron or steel parts are put in the phosphoric acid, the reaction causes hydronium ion to deplete, and the pH range rises, causing the salt to dissolve and fall out of the solution and get precipitated on the surface. The process is also known as phosphate conversion coating or phosphating. Here is an elaborative detail about different types of phosphating. ·          Iron Phosphating Iron Phos...
