Are GCSE materials resistant?
Are GCSE materials resistant?
The Edexcel GCSE in Design and Technology: Resistant Materials Technology is designed for use in schools and colleges. It is part of a suite of GCSE qualifications offered by Edexcel.
What are resist materials?
A photoresist (also known simply as a resist) is a light-sensitive material used in several processes, such as photolithography and photoengraving, to form a patterned coating on a surface. This process is crucial in the electronic industry.
What are resistant materials in design and technology?
In the field of Design and Technology, ‘resistant material’ is the term used for materials such as wood, plastic and metal. To describe a resistant material, think about its physical properties, appearance and keeping qualities.
What do you do in resistant materials GCSE?
A course in GCSE Resistant Materials (AQA) encourages students to design and make products with creativity and originality in a variety of practical activities, using a range of materials and techniques. A working knowledge of woods, metals, plastics and composite materials is required.
What do you mean by positive and negative resist materials in the lithography?
There are two types of photoresist, positive and negative resist, which are used in different applications. In positive resist, the exposed areas are solubly, in negative resist the exposed areas are insolubly for wet chemical development.
What are resistant materials examples?
Resistant materials are often sub categorised. For example, hardwood and softwood, thermosetting and thermoplastics, alloys and pure metals. Resistant materials require particular basic techniques to be used to enable materials to be measured, cut, shaped, joined, and finished when making products.
What are non resistant materials?
This unit is about developing learners’ understanding of the properties of selected non-resistant materials such as clay, paper, plaster, plastics, fibres and pliable metals and their related technologies. The choice will depend on the centre’s resources and facilities.
What is a photoresist material?
Photoresists are fundamental materials related to photolithography. They are light-sensitive materials, composed of a polymer, a sensitizer, and a solvent. Each element has a particular function. The polymer changes its structure when it is exposed to radiation.
