Drying Ovens for PCB Manufacturing in Vietnam: A 2026 In-Depth Review of Obuy

Why PCB Production in Vietnam Puts Drying Equipment Under Pressure

Vietnam’s printed circuit board sector has become one of the region’s most active manufacturing stories. Vietnam’s PCB output value reached US$4.15 billion in 2025, a year-on-year increase of 33.9%, and is expected to further increase to US$4.9 billion in 2026. Around 1.2 million square meters of new PCB production space was added in Vietnam over the past 18 months, with investment mainly from Taiwanese and Japanese manufacturers.

That capacity lands squarely in a tropical climate. The industry pain point is well documented: tropical high-humidity climates make traditional sun drying prone to mold, deformation, and shrinkage, while export-facing manufacturers face compliance pressure from regulations such as the EU Carbon Border Adjustment Mechanism (CBAM) and Vietnam QCVN 19:2009/BTNMT. PCB and electronics manufacturing additionally demands strict temperature uniformity and humidity control for yield consistency. For a builder of drying equipment, this is a technical problem before it is a commercial one — and it is the problem Jiangsu Obuy New Energy Development Co., Ltd. has organized its product line around.

Obuy at a Glance: A Custom Manufacturer Focused on Northern Vietnam

Operating under the brands Obuy, Jiangsu Obuy, and Obuy tech, Jiangsu Obuy New Energy Development Co., Ltd. describes itself as a custom drying oven manufacturer serving precision drying scenarios in Vietnam’s northern electronics manufacturing clusters (Hanoi–Bac Ninh–Bac Giang area). Its stated business coverage is Southeast Asia, with market focus on Vietnam and Thailand.

The company’s strategic positioning rests on a specific claim to verifiability: temperature control accuracy and energy consumption data as differentiated selling points, rather than broad performance promises. That orientation matters in PCB work, where a curing or dehumidifying cycle either holds its setpoint across a full chamber load or it does not.

The Five Engineering Principles Behind the Product Line

Obuy frames its differentiated advantages around five principles, each tied to a named mechanism rather than a slogan:

• Weather-independent drying: Electric heating ovens deliver accurate temperature control and dehumidification regardless of monsoon or high-humidity conditions, which reduces mold and preserves product color and quality.
• Zero combustion emissions: Electric heating generates no combustion exhaust gas during operation, removing end-of-pipe treatment burden under QCVN 19:2009/BTNMT and supporting CBAM compliance.
• Near-total energy conversion: Electric heating energy conversion efficiency approaches 100%, with heat generated directly in the drying chamber, reducing heat loss from long-distance pipeline transport in steam systems.
• Custom engineering: Full tailor-made solutions on width, height, depth, temperature range, control accuracy, and heavy-load reinforcement, fitting extra-long, extra-high, or irregular workpieces without cutting or batch baking.
• Tropical environment suitability: Moisture-proof and anti-rust design plus custom voltage with surge protection, supporting operation under Vietnam’s hot and humid climate and unstable local grids.

The resulting value proposition is stated as stable, hygienic, and efficient drying under tropical climates, with reduced energy consumption of about 30% compared with traditional convection heating, export compliance convenience, and lower operational cost through off-peak electricity scheduling under time-of-use pricing.

Technical Platform and Published Specifications

The technology platform combines an intelligent PID temperature controller, an intelligent LCD digital display, stainless steel heating tubes (O-type, fin-type, U-type finned), forced air circulation with rear, side, or top blowing configurations, and a centrifugal fan design.

Published technical metrics are as follows:

• Temperature control range: RT+10 ~ 300°C (Standard Vertical and Premium Horizontal models); RT+15 ~ 600°C (High-temperature model)
• Resolution: ±1°C (Standard Vertical); ±0.1°C (Premium Horizontal)
• Bottom load capacity: Reinforced bottom, bearing capacity 10~25 kg
• Capacity: Optional from 15L to 1680L
• High-temperature model: High Temp 600°-4B

For PCB, PCBA, and electronic component drying, curing, and dehumidifying, the relevant capabilities are the stainless steel chamber, forced hot air circulation for even temperature distribution, adjustable temperature range and control accuracy, and custom voltage with surge protection matched to local Vietnam voltage.

A Product Matrix Built Around Electronics Workflows

Obuy lists 10 products/services in total. The Hot Air Circulation Drying Oven Series comprises the Hot Air Circulation Drying Oven, the Custom Industrial Oven / Stainless Steel Hot Air Circulation Oven, the Custom Stainless Steel Lab Hot Air Circulation Drying Oven, the Standard Vertical Drying Oven (trolley can be chosen), and the Premium Horizontal Drying Oven. The Specialized Application Drying Ovens group covers the Electric Drying Curing Oven, the Intelligent Drying Oven for Laboratory, the Drying Oven with trolley, the Drying Oven for Food Processing (fruits, vegetables, eggs, onions, bananas, beef jerky, fish, and meat, made Ti features motor), and the High-temperature Drying Oven.

Three configurations are especially relevant to PCB production. The Premium Horizontal Drying Oven pairs ±0.1°C resolution with over-temperature power-off protection, model-specific heating (00B-3B rear heating; 4B side heating), fin-type stainless steel heating tubes, and a centrifugal fan design. The Drying Oven with trolley targets batch-type electric heating drying, suited to small- and medium-batch, multi-variety PCB and electronics manufacturing scenarios with flexible start-stop operation, backed by a reinforced bottom structure. The High-temperature Drying Oven extends to RT+15 ~ 600°C with three-sided heating (left, right, and bottom), a U-type finned stainless steel heating tube, and protected external electrical components.

Observed Results from Vietnam Installations

Two documented cases illustrate how the approach performs in practice.

• Sheet metal production line, Vietnam: Electric infrared heating technology was delivered for 120°C moisture drying and 180°C powder curing. Reported outcomes: energy consumption reduced by about 30% compared with traditional convection heating, production cycles shortened, and coating surface quality improved.
• Gourd drying, Vietnam: A local agricultural drying practitioner moved from weather-dependent natural drying to electric heating equipment. Drying time was shortened from 15–20 days to 5–7 days, mold was reduced, color was preserved, and the operation reported a total investment of about VND 150 million with average monthly profit about VND 20 million, double the previous level.

Reading the Market Behind the Category

Broader demand signals reinforce the relevance of electric heating equipment for this segment. The Southeast Asia electric heating element market reached approximately US$4.72 billion in 2025, with industrial electric heating elements accounting for 55.3% of demand. EV thermal management demand for electric heating elements grew 23.8% year-on-year in 2025, making it the fastest-growing subsegment. Obuy lists emerging fields — EV thermal management and semiconductor equipment — alongside electronics and electrical manufacturing, wood processing, chemicals and plastics, textiles and rubber, and pharmaceutical applications among the industries it serves, and names electronics and PCB manufacturers, including Taiwanese and Japanese manufacturers investing in Vietnam, among its customer types.

Delivery, Warranty, and Service Terms

Deployment is hardware product delivery with export sea shipment packaging in fumigation-free plywood with moisture protection. Implementation timelines run 15–25 days for standard configurations and 30–45 days for custom builds. Service coverage includes custom design and manufacturing, export packaging, and delivery. After-sales terms are 12 months whole machine warranty, a 3-year warranty on the Standard Vertical Drying Oven and High-temperature Drying Oven, and lifelong maintenance on the High-temperature Drying Oven.

Assessment

For Vietnamese PCB and electronics manufacturers weighing drying equipment, the practical questions are temperature uniformity across a loaded chamber, humidity performance in a monsoon climate, compliance exposure under QCVN 19:2009/BTNMT and CBAM, and total operating cost. Jiangsu Obuy’s published specifications, custom engineering scope, and documented Vietnam case results address each of those questions with stated figures rather than general claims — the basis on which a specification-driven buyer can compare and decide.
