Dishwasher Circuit Board Operation

What Is The Manufacturing Process Of Dishwasher PCB?

The dishwasher PCB manufacturing process consists of the following steps.

PCB Layout Design

First, you need to draw a schematic of this PCB. It is the outline of your circuit board design. Then, design the PCB layout by using reliable design software. Nowadays, various design software is used in designing dishwasher circuit boards.

Then, you have to convert this design file into Gerber format. The Gerber file contains all the required information related to PCB manufacturing. Besides, it is important to conduct a design rule checking for finding faults in the design.

After completing the checking, send the file to the manufacturer to handle the further steps.

Printing

In this stage, the dishwasher circuit board laminate needs to be washed. Then, it receives the photoresist that is composed of photoreactive chemicals. A UV-ray is dropped upon this board to perform the printing process.

Alignment of PCB Layer

After a successful primary etching, it is required to align the PCB layers. An automated optical inspection can be run for checking this layer alignment and other features of this PCB.

Binding Of Layers

In this segment, you need to bind PCB layers. The outer PCB layers should be connected to the substrate.

PCB Drilling

Now, it is time to drill holes on the stack PCB board. Here, maintaining the hole diameter and drilling speed concerning the shape of PCB components is essential. Usually, an X-ray is used in finding the proper placement of drilling.

Copper Coating

After drilling, a copper coating is applied to fill up the drilled holes. Besides, plating binds the layers together. Then, image the external PCB layers by applying photoresists once again.

Etching

Then, the board is placed in a toxic Ferric Chloride solution. It reduces unwanted coppers again. In this case, you must cover the necessary portions through a protective mask.

What Vias Are Used In Dishwasher PCB?

The dishwasher PCB vias play a crucial role in thermal management and signal transmission. Versatile PCB vias are used in this printed circuit board. The most used PCB vias include-

Through-hole Via

These PCB vias are applicable in through-hole technology (THT). Through-hole vias connect two outer layers (Top and bottom) of the PCB in dishwashers. It is a little bit difficult to maintain current conduction and to solder these vias.

Blind Via

Unlike through-hole vias and buried vias, these vias connect an inner PCB layer to the outer layer. It is required to define the holes for each level as a separate drill file. Here, the aspect ratio should be 1:1

Buried Via

PCB buried vias are placed in between two internal players. That’s why they are named buried vias. The suitable aspect ratio is 1:12 in this case.

Thermal Via

Thermal vias handle heat dissipation in dishwasher board modules. Excessive heat generation is injurious to PCB function. PCB thermal vias keep the components cool by improving thermal conduction.

You should have clear concepts on Via-in-pad, via-covering, drilled holes, etc, to optimize dishwasher circuit board vias.

• HASL (Hot Air Solder Leveling)
• ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold)
• Hard gold finish
• OSP (Organic Solderability Preservatives)
• Immersion Silver
• Immersion Tin

Except for OSP, the other surface finishes are metal-based. But ENIG is the most suitable among all surface coating mechanisms. It provides immense positive features to the dishwashers.

ENIG ensures reliable protection for PCB components from oxidation. Usually, PCB components suffer from oxidation due to moisture absorption in most cases. ENIG surface finish creates a protective layer outside the PCB surface free from oxidation.

Besides, this metallic coating supports the use of conformal coatings on the PCB surface. A suitable conformal coating protects the circuit board from chemical contaminants, moisture, and dust.

ENIG helps expand the PCB surface for dishwashers. So, it becomes easier for the manufacturer to place the PCB components as per designs. All of these positive points make ENIG one of the best metallic coatings of the dishwasher circuit boards.
