Working principle

A PCB drying oven adopts air forced convection system, hot air is evenly distributed throughout the chamber. The oven is designed to baking electronic components in SMT production line.


When the oven is turned on, a heating element, begins to heat up. As the element gets hotter, it heats up the air inside the oven. This hot air then rises and circulates throughout the chamber, drying the samples or specimens placed inside.


The oven also has fans or blowers that help circulate the air more quickly and uniformly, a temperature controller is used to regulate the temperature inside the oven and prevent overheating.


The PCB drying oven has a timer that allows the user to set the drying time required for the particular samples or specimens. Once the set time finishes, the oven turns off automatically.


Overall, the PCB drying oven is a simple but effective instrument to dry electronic components in electronic manufacturing industries.


Structure

A PCB drying oven, also known as PCB baking oven, is a type of oven that uses a blower to circulate hot air inside the oven. The structure of the oven typically consists of the following parts:

Exterior oven: The body of a hot air oven is usually made of cold rolled steel plates for durability and easy maintenance.


Interior oven: The inner oven is the space to place samples. It is also made of stainless steel SUS304, and it is designed to evenly distribute the heated air throughout the chamber.


Heating Element: The heating element is responsible for generating heat inside the oven.


Fan: The fan circulates hot air throughout the oven to ensure even hot air distribution.


Control Panel: The control panel contains temperaturec controller that allow you to adjust the temperature, time, and other settings.


Door: The door is made from tempered glass with a handle that provides easy observation.


Overall, the combination above parts work together to create a uniform and efficient heating in this oven.


Feature

Here are some of the key features of a PCB drying oven:

• Even heating: A PCB drying oven uses a system of heating elements and fans to deliver hot air uniformly to the surface of the printed circuit board. This ensures that the board is dried or cured evenly, which is critical for high-quality electronic components.


• Precise temperature control: A PCB drying oven uses a digital control panel to precisely control the temperature and drying time. This ensures that the board is exposed to the correct temperature and duration for optimal drying or curing.


• Adjustable racks: A PCB drying oven typically has adjustable shelves to accommodate different sizes of printed circuit boards. This feature ensures that the boards are evenly spaced and exposed to the hot air for optimal drying.


• Stainless steel construction: A PCB drying oven is typically constructed with stainless steel on the interior surfaces for durability, easy maintenance, and resistance to corrosion.


• Safety features: A PCB drying oven typically features safety measures such as over-temperature protection to protect the oven from overheating.


Application

PCB drying oven is commonly used in electronic manufacturing industry, to dry electronic components (Printed Circuits Boards), and cure coatings, adhesives, and other materials, here let’s illustrate how a PCB drying oven is used in SMT industry:

SMD package may get damp due to climate reasons, long-term storage or improper storage, the moisture inside the package will vaporize and expand due to reflow soldering heating, this may cause damages, like wiring disconnection, or reduced reliability, this is called the "popcorn" phenomenon.

In J-STD-033 standard, it suggests SMD packages can be baked at 125 deg C to recover their floor life, the baking time differs as per MSL/package body thickness. The drying oven is the optimal choice, it provides different temperature baking from 50 deg C to 125 deg C, and effectively expel moisture from MSD packages, this greatly helps manufacturers to improve production efficiency, and avoid the huge loss of products recall due to substandard quality.


What causes a PCB drying oven overheat?

There are several reasons why an oven may overheat, including:

•Malfunctioning thermostat: The thermostat is responsible for regulating the oven temperature. If it's faulty, it may not accurately read the temperature, resulting in the oven heating up beyond the set temperature.


•Broken heating element: The heating element provides the heat needed for cooking or baking. If it's broken, it may continue to generate heat even when the oven is turned off, causing it to overheat.


•Blocked air vents: The air vents are necessary for proper air circulation in the oven. If they're blocked, the heat will remain trapped inside, causing the oven to overheat.


•Damaged door gasket: The door gasket seals the oven door tightly and prevents heat from escaping. If it's damaged, heat may leak out, causing the oven to overheat.


Overall, it's important to regularly maintain your oven and address any issues as soon as they arise to prevent overheating and to ensure safe operation.


Frequently asked questions

Q: How do I clean a PCB drying oven?

A: Cleaning a hot air drying oven depends on the type of material used to build the oven. You can clean the interior of the oven using mild cleaning agents or soapy water, and the racks and trays can be washed in a dishwasher. It is essential to clean the oven regularly to maintain its efficiency.


Q: How does a PCB drying oven work?

A: A PCB drying oven works by circulating heated air to remove moisture from the items placed inside the oven. A fan inside the oven blows air over the heating element, which heats the air. The heated air then circulates around the oven's interior, removing moisture from the items inside.


Q: How do I maintain a PCB drying oven?

A: Maintain a PCB drying oven by performing regular inspections, checking and replacing any worn-out parts, and performing regular cleaning. It is recommended to schedule routine maintenance and checks to ensure the oven remains in working condition.
