This equipment can significantly demonstrate that the leadframe module, following plastic sealing, has passedthe automotive-grade lamination confimement level 1 reliability test. This is to meet the requirements ofautomotive-grade severe application, and the thickness of the tin plating layer is CPk 1.67.

Allmerit High Speed Plastic Package Lead Frame Tin Plating Equipment

The tinning equipment of this type can realize the integration of automatic production, including electrolytic softening, high-pressure water knife, high-speed tinning and unloading, by clamping and fixing the plastic encapsulated integrated circuit lead frame on the continuously running transmission steel belt via the loading system.

It belongs to a new type of environmentally friendly, energy-saving and water-saving electroplating equipment, which completely overcomes many defects of traditional rack plating equipment, including many working procedures, unstable product quality, uneven coating, serious pollution of waste water and waste gas, high electroplating cost, large consumption of chemicals, and many workers.

Equipment performance parameters

It is suitable for materials with a width of 30-110 mm, a lead frame substrate thickness of 0.15-1.0 mm, and a plastic packaging thickness of 1.0-10 mm. The strip speed is adjustable between 3-12 m/min (based on the product), and the tin plating thickness can reach 4-15 microns.

In addition, according to customer requirements, the process can be customized based on product characteristics. The SECS-GEM protocol can be built in to facilitate access to the customer's production management system. A maintenance reminder function can also be configured to make equipment maintenance more intelligent.

Instructions for Selection of Loading Mechanisms (Three loading mechanisms are available for customers to choose from based on their actual needs)

Manual loading mechanism: The equipment offers high cost-performance ratio and low initial investment. It features simple loading operation and maintenance, low requirements for operators and maintenance personnel, and easy switching between different products for tinning production. It is more suitable for electroplating OEM enterprises and packaging enterprises that have requirements on the cost-performance ratio of equipment.

Semi-automatic cutting and loading mechanism: The loading operation is simple and has low requirements for operators. The equipment offers relatively high cost-performance ratio and can switch between multiple products for production. It is suitable for packaging enterprises and electroplating OEM enterprises that have certain requirements on equipment automation.

Fully automatic cutting and loading mechanism (manual loading can be switched): This equipment has a high degree of automation. The loading operation is convenient and suitable for large-scale tinning production of products. The equipment control software is powerful, capable of storing production parameters for different products and switching between products with one click. Utilizing Aomeite's unique patented technology, it can immediately switch to a manual loading system to accommodate the short-term increase in production. It is suitable for packaging enterprises and electroplating OEM enterprises that conduct large-scale and batch production.

Instructions for Selection of Equipment Structure (Flexible customization based on the actual layout of the customer's factory)

Linear tinning equipment: Simple operation and convenient maintenance; long service life of the steel belt and long line body; low initial investment and high cost-performance ratio.

U-Type tinning equipment: The equipment line is short, and the loading and unloading mechanisms are on the same side of the equipment, facilitating attendance and management, and making operation and maintenance more professional.

Circular tinning equipment: The equipment line is short, and the unloading mechanism is set in the middle of the equipment (can be flexibly customized according to the site).

Dual-channel tinning equipment: Compared to two separate sets of equipment, the equipment line has a smaller size and occupies less space. Operating in dual-channel mode, it can produce two types of products simultaneously or increase the production capacity of a single product.

Highlights of Equipment Structure

Advantages of Tinning Process Section: The segmented control of tinning water ensures a more uniform liquid level. The special reflux design of the lower tank reduces foam production and ensures sufficient mixing, leading to a higher uniformity of chemical solution concentration.

Advantages of High-pressure Water Process Section: Five-stage filtration ensures that the water supply is completely clean, preventing nozzle blockage. The partitioned design of the reflux tank ensures gradual water filtration. The high-pressure water spray coverage of over 110mm enables more effective cleaning. The spray plate can be conveniently replaced according to product design.

Advantages of Water Washing Process Section: The design of the water spray direction and angle prevents water crossover. The quick-release design of the spray pipes and nozzles makes maintenance more convenient.

Advantages of Loading and Unloading Sections: Two fully automatic unloading methods are compatible, suitable for different sizes of material boxes. Fully automatic loading and unloading as well as automatic material box rotation. The AGV cart conveys the material box, and the robotic arm automatically positions and grabs to complete the entire set of fully automatic loading and unloading actions.

Usage of Online AOI: We uniquely apply online AOI inspection technology to tinning equipment to reduce losses caused by defects in the electroplating process.

Software and Control Optimization

Alarm Statistics Function: It can count the number of occurrences of each alarm and the cumulative time of the alarm, which allows for a more intuitive understanding of the equipment's problem points and enables more precise maintenance, improvements, and upgrades of the equipment.

Maintenance reminder function: this function can be added to every wearing part to remind customers to conduct timely maintenance of the equipment, thus ensuring the quality of the product.

This set of tinning equipment has been improved in many aspects compared with early domestic and foreign equipment: the optimization of the upper tank body mechanism, including the shielding structure, high-pressure water knife, and water washing structure; the control software operation is more convenient, including the acquisition, import, and export of production line parameters, which is more convenient for traceability analysis; the brand-new automatic loading and unloading mechanism greatly shortens the manual participation time, and the material change operation has been shortened from 2-5 minutes to over 40 minutes, realizing one-person multi-machine operation (one person can operate 8-12 machines), greatly reducing labor costs.
