Which Specifications Should You Consider During Digital Thermometer PCB Layout Design?

Like every other sort of PCB, you need a proper layout design for the thermometer PCB. And this layout has some defining factors which one should not neglect.

As a result, we need to check out the layout design’s specifications.

Base Material

It is ideal that the thermometer PCB has a base material of FR-4. This is because the FR-4 possesses features that boost the reliability and quality of the PCB.

Placement of Components

Remember that you have a board with minimal spaces, and the board will need to accommodate several components. This is why component placement is a requirement.

The placement of components should make routing much easier and support the standard requirements of the PCB.

With regards to component placement, the following are a few considerations

  • It is best to reduce the number of crossing nets. When crossing nets dominate, it makes it difficult to route the PCB according to standards.
  • Although the thermometer PCB will contain several components, some should come first. This is because these will be the most important components in the PCB. So you will need to place them first in the PCB to ensure appropriate positioning.
  • The surface mounting devices are components that will also feature on the board. Good practice demands they all remain on one side of the PCB.
  • Large ICs and processors should take central positions in the PCB as this will enhance the ease of routing.
  • To further make routing easier, let connected pads face each other.

Other things to consider include;

  • Avoid traces that are too thin. They have so many downsides and make the process tedious for the manufacturer.
  • Let the trace width be in line with the speed signal. This will help establish impedance control.
  • Ensure to use wider trace widths for boards needing higher currents.

How Do You Test Thermometer PCB?

It is common practice to test the PCB before it leaves the manufacturer’s location.

There are several tests for the thermometer PCB which you can employ or ensure the manufacturer employs.

Incoming Quality Control(IQC)

This is a way of testing the materials even before the production of the PCB. Incoming quality control is a proactive measure that will affect in the following ways;

  • Discover material problems at the very early stages
  • Minimizes risk of future failure or issues
  • Minimizes quality cost

In summary, it ensures quality materials and measures begin the first production phase.

In-Process Quality Control

This involves checking the quality of the PCB during the production process. That is, testing while production is ongoing.

The IPQC ensures that the materials and processes all follow the standard rule and practices. Inspection and tests are carried out to audit the PCB at the different production phases.

Automated Optical Inspection(AOI)

For example;

An industrial thermometer PCB  will require high-temperature tolerance. Other items that will feature in the schematic include;

  • Microcontroller
  • Thermocouple
  • Integrated circuits suitable for cold- junctions

In the case of a domestic thermometer PCB, the thermistor can replace the thermocouple. Consider these factors and make the schematic using industry-standard software.

Create The Layout

The next phase is to create the layout using the determined schematics from the software. This will involve the following;

Thermometer PCB Layout

Thermometer PCB Layout

  • Get the software to produce all footprints and necessary parts. This is necessary because the footprints direct the dimensions of each component part of the PCB.
  • Manual or automatic routing of wires should follow
  • Label each component part in the layout

Etch/Impress The PCB

This is getting your thermometer PCB layout into the board material from the software. It involves the following steps.

  • You need to print out your layout on an A4 glossy paper, although photo paper will also suffice.
  • Cut your PCB sheet, which should be in correlation with your layout. As a result, it must have the same dimensions as your layout.
  • Treat the PCB sheet, which is usually a copper sheet. Apply steel wool on the sheet to remove oxide layers as well as photoresist.
  • Align the layout printout and the copper sheet(board). It must be perfect.
  • After placing them in the right position, use a hot iron to press the A4 glossy paper. It will transfer all that is in the printout to the board.

Introducing Vias To The PCB

The vias are holes on the PCB that serve as the wires’ path. You will need the drilling specifications from the layout software.

PCB Vias

PCB Vias

You can then drill the vias automatically or manually. In addition, there are specialized machines that will help you drill the vias. Finally, it would be best to obey standard rules and dimensions when drilling the vias.

Soldering PCB Components
