Rectangular frame quartz cleaning boat

The rectangular frame quartz cleaning boat is a precision quartz consumable designed specifically for high cleanliness cleaning processes. This product is made of high-purity quartz material and precision processed into a stable rectangular frame structure, which has excellent high temperature resistance, corrosion resistance, and thermal shock resistance. It is widely used in the wet cleaning and high-temperature annealing processes of wafers, silicon wafers, and various precision components in the fields of semiconductors, photovoltaics, and precision electronics. It can effectively carry and protect workpieces, ensure pollution-free cleaning processes, and is an ideal choice for improving yield and process stability.

FAQ

Q1: What is the maximum working temperature that this quartz cleaning boat can withstand?

A: Our rectangular frame quartz cleaning boat is made of high-purity (purity ≥ 99%) fused silica, with a softening point of up to 1730 ℃. It can work stably in a high temperature environment of 1100 ℃ -1200 ℃ for a long time, and can withstand higher temperatures in a short time, fully meeting the needs of various high-temperature cleaning and annealing processes.

Q2: Does it support customization of non-standard sizes and special hole positions?

A: Fully supported. We have a professional technical team and precision machining equipment, which can customize different length, width, height dimensions, frame wall thickness, bottom support structure, as well as various positioning holes, hanging holes and other details according to the drawings or specific process requirements provided by customers, ensuring perfect compatibility with your automated cleaning equipment or load-bearing fixtures.

Q3: What is the corrosion resistance of quartz cleaning boats in strong acid and alkali cleaning solutions?

A: Quartz materials have excellent chemical stability and have strong corrosion resistance to most acids (such as sulfuric acid, nitric acid, hydrochloric acid) and alkaline solutions, except for hydrofluoric acid and hot phosphoric acid. In conventional RCA cleaning, acid washing or alkali washing processes, metal ions will not precipitate, which can effectively avoid secondary pollution to the cleaned workpiece.

Requirements and Problem Solving

For users in the semiconductor, photovoltaic, and precision optics industries, metal ion pollution and particle residue in the cleaning process are yield killers. Our rectangular frame quartz cleaning boat is designed to solve these core problems. It can solve the following problems for you:

Eliminate secondary pollution: High purity quartz material ensures that impurities do not precipitate in acidic or high-temperature environments, ensuring the ultimate cleanliness of wafer or chip surfaces.

Enhance load-bearing stability: The stable rectangular frame design prevents thin sheet workpieces from warping, stacking, or slipping under high-temperature liquid erosion.

Extended consumable life: Excellent thermal shock resistance makes it less likely to explode during frequent hot and cold alternating cleaning, significantly reducing the cost of consumable replacement and downtime risk on the production line.

Core application scenarios

This product is mainly used in wet cleaning tanks, ultrasonic cleaning machines, and high-temperature ovens in the following high-precision manufacturing fields:

Semiconductor manufacturing: used for RCA standard cleaning, acid washing, and deionized water rinsing of silicon wafers and wafers.

Photovoltaic industry: Bearing and cleaning in the velvet cleaning and diffusion process of solar cells.

Precision optics and electronics: Ultrasonic cleaning of precision components such as filters, glass substrates, and ceramic substrates.

Advantage

Ultra high purity material: High quality and high-purity quartz sand is selected, with SiO2 content ≥ 99% and extremely low bubble and impurity content, ensuring the purity of the process environment.

Precision structural design: The rectangular frame structure has been mechanically optimized to ensure sufficient mechanical strength to support densely arranged workpieces, while maximizing the flow area of cleaning solution and avoiding cleaning dead corners.

Excellent thermal stability: The extremely low coefficient of thermal expansion allows it to withstand drastic temperature changes, and it maintains structural integrity even when taken out of the high-temperature annealing furnace and directly into the cleaning tank.

Comprehensive specification and size customization service

We are well aware that the equipment tanks and process requirements of each factory are not the same, so we provide in-depth customized services:

Size customization: Supports customization of any length and width from tens of millimeters to over one meter, accurately matching your cleaning tank body.

Structural customization: Special slots, grids, or hollow bottoms can be designed according to the shape of the workpiece (such as square or circular pieces) to prevent workpiece adhesion.

Customization of accessories: Quartz hooks, handles, or positioning pins can be added for easy gripping by robotic arms or manual operation.

Solve practical problems in applications

In actual production, many users face the problem of ordinary quartz boats being prone to deformation and severe crystallization, leading to particle detachment and product contamination. Our rectangular frame quartz cleaning boat eliminates internal stress through a special annealing process, greatly enhancing its resistance to crystallization. Meanwhile, in response to the buoyancy and impact forces generated by the flow of cleaning solution, our optimized frame crossbeam design can effectively prevent creep deformation of the boat body at high temperatures, ensuring a highly consistent cleaning effect for each batch.

Customer Application Case (Anonymous)

Customer background: A well-known semiconductor packaging and testing enterprise (located in Southeast Asia), mainly engaged in wafer level cleaning of high-end chips.

Facing difficulties: The ordinary quartz cleaning basket previously used by the customer is prone to microcracks under frequent high-frequency ultrasonic cleaning and high-temperature sulfuric acid immersion, and has a short service life (averaging only one month). Frequent replacement leads to production line shutdown, and occasional quartz debris causes chip scrap, resulting in heavy losses.

Solution: After understanding the specific tank size (800mm, 600mm, 400mm) and wafer carrying capacity (25 pieces per basket) of the customer, we customized a thick rectangular frame quartz cleaning boat for them. We have added reinforcing ribs at the bottom and performed special polishing treatment on the edges to reduce particle adhesion.

Application effect: After 3 months of on-site verification, this cleaning boat has remained intact and undamaged after hundreds of cold and hot cycles and strong acid corrosion, with no visible crystallization phenomenon. Customer feedback shows that the product yield has increased by 0.5%, and the lifespan of consumables has been extended to over 6 months, significantly reducing annual operating costs.
