How to Maximize your PCB Panel Utilization
PCB troubleshooting and repair involves visual and electrical inspections using various tools such as a multimeter, LCR, and, oscilloscope.
The solder is melted using either a wave soldering machine or a reflow oven or a normal soldering iron and this molten solder is then used to solder wires or electronic components on to the PCB or Printed Circuit Board. After assembly of electronic components the board is called PCB Assembly ...
If you need to adjust the trace width, pressWwhile routing and set the width to your desired value (15-20 mils in this case). Continue routing until you connect the trace directly to the3.3Vvia. To automate this routing process, readhow to autoroute a PCB layout in KiCad using the Fr...
Understand the importance of impedance in PCB design and how it affects signal propagation and power transfer. Learn techniques like using low-impedance components, optimizing trace lengths, and employing ground planes to reduce impedance. Utilize SPICE simulations, AC frequency sweeps, transient a...
BOM information: The assembly house needs information that enables them to either order the parts or organize the parts that you provide. Solder mask: You need to submit Gerber files that identify the areas of the board (e.g., pads for IC pins) that must receive solder during the process...
1.1 VLSI 是 超大规模集成电路(Very Large-Scale Integration的缩写) 1.2 EDA 是 电子设计自动化 (Electronic Design Automation) 2 Why and How: 我们为什么需要VLSI EDA以及各环节中简单内部原理(以CPU设计为例) 2.1设计芯片规格(Design Specification) 2.2硬件设计描述(Hardware Description) 2.2.1 设计库的高效...
If the board construction allows (mainly no heat sensitive components on the bottom side of the PCB directly under the connector) we try to drive heat from the bottom up through the PCB. This will facilitate the reflow of the solder connecting the center ground strip. This also eliminates the...
A rework process can be derived by using such a fixture and clamping it with minimal force initially, bake in the fixture at 105C for 4 hours, then add a little more pressure to the clamps and then spray-flux and re-reflow the CCA and allow to cool while still clamped in the fixture...
