Photocad app SMD stencils are required in the process of printing solder paste onto circuit boards in the electronics industry. The thickness and aperture of the SMD stencils define the amount of solder paste. To ensure that the solder paste adheres to the circuit board, close attention must be paid to the area ratio and aspect ratio of the stencil. photocadCALC software makes it quick and easy to calculate the maximum possible thickness for laser-cut SMD stencils with a variety of stencil apertures. However, the photocad app has a great deal more to offer: the product advisor allows you to specify the most suitable SMD stencils for your planned deployment. As a result, you will receive a link to our online shop that is tailored to reflect your specific needs, and which can be conveniently shared by e-mail, WhatsApp or Airdrop. A useful glossary, a tool to quickly define stencil thickness, and constantly updated news and information about the company and the online shop complete the range of functionalities offered by the photocad app.

Design Materials is an offline material reference guide trusted by hundreds of Engineers, Architects and Designers all over the World. The App was created to be a personal tool to help me take design decisions during the concept ideation of industrial products, in particular for 3D printing. Due to high demand, I decided to make it public and share it's information and power. Basically, it provides the fundamentals for most design/engineer materials on the market, based on reliable and curated academic sources. In addition, you can now create and manager your own Material, Resin or Filament data. Finally, the App features Apple Intelligence (AI) with a pair of Entity Masters in material engineering and STEM: HAL 9000 and Elemento, which can be accessed 24/7 while being on or offline (no internet). The guide contains material categories such as polymers, metals, naturals and more. All of these include synthetic, organic, bio-degradable, plastic, and much more subcategories. Each material contains information such as: About, Properties, Tags, Applications, Types and Photos. HAL 9000 & Elemento (AI entities): The legend of HAL is back. Ask anything from space to robotics or biology, HAL and Elemento are Gods of material engineering and science. HAL does precise flawless analysis while Elemento brings fresh human creativity with an attitude. In addition, you can choose the Tone of AI: Formal, Friendly, Direct or Arrogant. Both AI Entities work offline 24/7. Other features includes: • AI Chat with HAL 9000 or Elemento • Material Packs (subscribers) • 3D-model viewer/import/export • Object Capture: Scan Objects • Favorites section • Offline reference (no Internet needed) • Long list of properties per material • Save Notes per material/resin/filament • Create Designs using Apple Pencil • Support for all iPhone screen sizes • Dark Mode • iPadOS support • MacOS support • Continuous Updates with New Content • UNIVERSAL PURCHASE - One Payment for all Devices New Pro version auto-renew subscriptions: - 1 year (Gold) | 3 month (Silver) | 1 month (Bronze) subscriptions* - Access to all material database ABOUT SUBSCRIPTIONS • Payment will be charged to iTunes Account at confirmation of purchase. • Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. • Account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal. • Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase. • Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription to that publication, where applicable. • Terms of use (EULA): https://www.termsfeed.com/live/faff17b4-8765-4690-b57e-9aabde3d2950
