Transmission Lead-Frames

Xiamen Hongyu Intelligent Technology Co., Ltd. also focuses on the semiconductor precision sealing and assembly field. Transmission Lead-Frames, as the core interconnection carrier of high-speed signal transmission modules, relies on mature precision stamping and surface passivation processes to maintain circuit connectivity and suppress signal transmission loss fluctuations. They are suitable for demanding high-speed packaging conditions, helping your signal chain operate stably and reliably.

Component Function Explanation

It is a precise stamped lead frame that carries chips and realizes the interconnection transmission of electrical signals. It belongs to the key substrate of semiconductor packaging. In high-speed packaging, frame size deviations and coating defects are prone to cause signal attenuation, short circuits, and报废. The product is made by integrating high-conductivity base materials through one-piece molding， completing signal conduction and conduction through precise pin arrangement， while also serving as a heat dissipation and structural support function. It is widely compatible with optical communication， radio frequency transmission and reception， and high-speed data transmission devices. Pin accuracy directly determines the packaging yield and signal stability， and is an indispensable core component in high-speed packaging.

Process Strength and Performance Highlights

1. High-frequency impedance matching design to ensure signal integrity

Based on packaging simulation experience， we conduct impedance verification at the layout stage to avoid sudden changes in high-speed transmission impedance. In 25G/50G links， we suppress signal reflection and crosstalk to ensure stable signal quality in high-frequency conditions.

2. Stable coating interface， compatible with reflow soldering cycles

Coating schemes such as nickel-palladium-gold and silver plating have been verified through thermal cycles. The coating adhesion is excellent， and it is not prone to peeling or discoloration. It also takes into account solderability and corrosion resistance， reducing the risk of soldering failure during assembly.

3. Production consistency control to reduce batch deviations

The production line is equipped with online size monitoring， closed-loop control of pin coplanarity and spacing， simultaneous compensation for mold wear， and strict control of batch size fluctuations to ensure stable soldering yield for customers and reduce debugging costs.

4. Clean production process to meet high-reliability packaging requirements

The workshop implements zone control of pollution sources， plasma cleaning after molding to remove organic residues， reducing the risk of plastic encapsulation delamination， and adhering to clean control standards that match the communication semiconductor packaging entry criteria.

FAQ

Do you offer technical support and selection services?

Support. We can combine your packaging solution, signal rate and reflow soldering process to assist in comparing the base materials and coating schemes, proactively assess the impedance risks brought about by the pin layout, provide suitable selection suggestions, and simultaneously cooperate with simulation data for verification.

Is there a warranty?

Under the conditions of standardized warehousing and normal packaging and processing, within 12 months after the product leaves the factory, if the defect is caused by raw materials or process flaws, replacement can be provided; however, oxidation and deformation resulting from customer's secondary processing or improper storage are not covered by this guarantee.

Do you accept small orders?

We can accept sample orders and small-scale trial production orders. For small orders, the delivery time is faster as no mass production molds need to be made; for custom orders, due to the cost of molds, the price will differ from large-scale orders, and they are suitable for project verification in the early stage.

Provide export documents?

We can provide the entire set of commercial invoices, packing lists, origin certificates, RoHS material reports, and can also provide third-party testing certificates such as SGS as per your needs, to meet the requirements for customs clearance and project filing and review.

How do we ensure the quality?

In addition to the routine size and coating inspections, we have added solderability tests and salt spray accelerated verification for the lead frames. Sample pieces are retained for traceability in each batch. You can also specify a third-party institution for independent inspections, and the production line review will also be made available simultaneously.

What services can we offer?

Support custom development of drawings, rapid prototyping, fine-tuning of coating schemes, small-batch trial production, and mass production delivery; at the same time, provide consultation on packaging processes and assistance with failure analysis, helping you troubleshoot packaging issues such as welding, layering, and signal abnormalities.

Did your products undergo testing before being shipped?

Final inspection is carried out before each batch of goods is dispatched. The key inspections include checking the alignment of pins, the thickness of the coating, and the cleanliness of the surface. Sample tests are conducted to verify the solderability, and the corresponding batch inspection report is attached and sent along with the goods.

Do you offer technical support?

Throughout the entire process, there will be comprehensive technical coordination. During the initial selection assessment and prototyping stage, parameter confirmation is carried out. In the later stage of packaging and debugging, if there are issues such as welding or signal integrity problems, engineers can be arranged for coordination to provide analysis and suggestions.
