The PCB’s in today’s smartphones contain an ever-increasing density of components and integration. The iPhone uses “Substrate-Like” PCB technology to achieve impressive levels of component density, everything is so closely packed, and no space is wasted. With this PCB technology, a "PCB sandwich" could be made by creating cavities in an FR4 PCB substrate and then stacking another PCB on top to form a lid, the “walls” formed by the cavities can be plated and then used as interconnects. This is similar to hollowing out the inside of a loaf of bread and then filling it with cheese & ingredients – or components in this case! Standard FR4 substrates A clever and smart PCB technology for the modern smartphone. Apple has been using Substrate-Like PCBs since the iPhone X and has been evolving and iterating it with every new iPhone release. It will be interesting to see how this concept is implemented now with the new iPhone 15, looking forward to seeing iFixit next teardown! #b3d #blender3d #geometrynodes #iPhone15Pro #iPhone15 #simulation #electronics #Engineering #hardware #Smartphones #science #kicad #altium #freecad #Eevee #pcbdesign #manufacturing #technology #art

Rendering some of my previous work with Eevee Next! Very impressed with it so far, I simply loaded my old blend file and worked straight away! Also, the compositor can run on the GPU! exciting times ahead!

One of the best ways to showcase a PCB design is to animate components falling on the PCB, here are three different animations I created with Blender featuring the ZSWatch open-source smart watch. These animations are all programmed by using Geometry Nodes, so everything is fully procedural and customisable. #b3d #geometrynodes #electronics #pcb #smartwatch #technolgy #freecad #kicad #3dmodelling #render #simulation #3dart

You can use Blender's geometry nodes to solve physics and electromagnetic equations such as Biot-Savart law. You can calculate the magnetic field of a coil anywhere in 3D space and visualise the magnetic fields. Additionally, you can see in real-time how the magnetic field lines change as the coil gets deformed and twisted! #geometrynodes #b3d #blender3d #electronics #Engineering #Science #physics #kicad #circuits

I’ve created procedural generators of ICs and connectors using geometry nodes. Due to the large number of different packages of ICs and connectors, it might be better to generate their models as and when needed rather than storing an unlimited number of unique 3D models. Also using the new hobby mat material from Chipp Walters #b3d #geometrynodes #blender3d #electronics #engineering #science #kicad #circuits #pcbdesign #manufacturing #technology #3dmodeling

very excited to share what I've been working on, I've created an addon which allows you to run FastHenry directly in Blender! you can use the power of Blender to create any curve object and then call FastHenry to simulate the resistance and inductance. This demo video shows how you can calculate the resistance and inductance of a bond wire in a power module. You can experiement with different shapes and curvatures and see how the inductance changes. Furthermore you can control the radius with geomotry nodes! Also, you can combine this with ElectroMag Nodes to then visualise the magnetic fields! This addon will be a free update to ElectroMag Nodes #b3d #blender3d #geometrynodes #inductance #electronics #hardware #science #engineering #pcbdesign #educational #magnet #kicad #freecad #altium Maurizio Di Paolo Emilio hackaday

Testing Electromag Nodes on Apple M4 mac mini, very impressed with its performance in handling a complex scene like this. The magnetic field calculations are updated in realtime with no lag in EEVEE with a compositor node setup.

You can now use Blender Fasthenry to do PCB layout studies, calculate impedances of loops and return paths and determine how many vias you need! This demo shows how the impedance of DC decoupling capacitor is impacted by its distance from the IC, and the number of vias under the IC and near the capacitor. This is for a two-layer 1.6mm PCB at 1MHz. Blender FastHenry is now a solid tool for layout simulations and impedance calculations, available on Github. #b3d #geometrynodes #engineering #science #electronics #Simulation #kicad #altium #hardware #technology #3dmodeling #pcbdesign hackaday Maurizio Di Paolo Emilio

continuing with my PEEC solver in Blender for inductors. Now I have a basic Python/Numba code that can calculate skin and proximity. You can see as the frequency increases the current shifts towards to the outer surface and also gets affected by adjacent turns #b3d #geometrynodes #electronics #Technology #science

Wire bonding and lead impedance calculation in Blender FastHenry! I've improved how the simulation results are visualised, the entire objects now gets overlaid with a colour rather than using bound boxes.

New update on combining FastHenry and Blender 🔶 , I've added the ability to calculate the mutual inductance between objects! Also developed a basic UI inside Blender to visualise the results and to highlight the inductively coupled objects. This video shows some examples of what can be donw now. First demo shows how you can model the impedance of die bond wires and the coupling to adjacent wires, you make adjustments to their lengths and curvatures and see the results in near-real-time. Second demo shows calculating inductances and mutual inductance of air-core inductors with arbitrary positions and deformations. Third demo shows simulating PCB coils over a range of frequencies for applications such as wireless power and distance sensing. And you can combine this with Electromag Nodes to visualise the magnetic fields! #b3d #blender3d #geometrynodes #electronics #hardware #science #technology #pcbdesign #kicad #altium #ansys #3dart #programmer #python #engineering #semiconductors #circuits #inductors #components
