Product Details
A-TECH strives excellent quality by attaching great importance to details in the production of Aluminum PCB.
Company Advantages
1. The design of A-TECH osp coating pcb takes into account many factors. It includes statics, dynamics, the strength of materials, vibrations, reliability, and fatigue.
2. The product is non-toxic and causes no harm. All of its parts and ingredients are made of nontoxic and environmental-friendly raw materials, including filter membrane, and the Nanosilver antibacterial powder used in it.
3. The product has the advantage of Electromagnetic Compatibility (EMC). It has been totally tested, minimizing the risk of interference to the radio spectrum.
4. People do not have to worry that shampoos, vinegar, hair dye, or other liquids will affect its functions or make it fade.
5. If people want to keep their electricity bills down or otherwise go green, choosing this product with great efficiency levels will be a great choice.


Immersion Tin, or Chemical Tin, it’s a RoHS Compliant metallic finish deposited by a chemical displacement reaction that is applied directly over the basis metal of the circuit board, the immersion Tin protects the underlying copper from oxidation over it’s intended shelf life, copper and tin however have a strong affinity for one another, the diffusion of one metal into the other will occur inevitably, directly impacting the shelf life of the deposit and the performance of the finish. The negative effects of tin whiskers growth are well described in industry related literature and topics of several published papers.

The typical thickness of Immersion Tin is ≥1.0UM and the shelf life is 6 months. The cost of Immersion Tin is more expensive than HASL but less expensive than Immersion Gold and close to Immersion Silver. Similar to Immersion Silver, Immersion Tin is also sensitive in handling and storage, it requires PCB manufacturers to control and pack PCBs with Imm Tin more carefully.



The advantages of Immersion Tin

● Excellent flatness
● Mid range cost for lead free finish
● Good for fine pitch / BGA / smaller components
● Top choice for press fit technology
● Reworkable



The disadvantages of Immersion Tin

● Very sensitive to handling – gloves must be used
● Exposed Tin on final assembly can corrode
● Not good for multiple reflow/assembly processes
● Aggressive to soldermask – soldermask dam should be more than 5mil
● Baking prior to use can have a negative effect



A-TECH is capable of using Immersion Tin, we make the profile and electrical test before the process of Immersion Tin finish, and we use papers to separate each piece of boards to avoid scratches during package and transportation.

A-TECH osp pcb finish is produced under strict scrutinization. It is checked for its material ingredients as well as material extraction methods to guarantee its quality. It is available in different dimensions meeting the USA and Euro standards
The production of A-TECH immersion silver pcb finish covers a few steps. The rough concentrate is deeply processed at first to extract some useful ingredients, then the concentrate is further ground for higher purity. The product is easy to clean and maintain with a damp cloth
High-tech processing equipment is used in the production of A-TECH osp pcb finish. It is done under the detritus equipment, grinding equipment, as well as sand-making equipment, which can guarantee high purity and fineness. It meets the requirement of food safety standards
The raw materials of A-TECH carbon ink pcb are treated with several procedures. Materials enrichment, refining, and smelt process will be conducted to make the materials into a product with high purity. The product is made of AISI 304 food-grade stainless steel, which contains no toxic substances
A-TECH carbon ink pcb will go through several manufacturing stages. First, the raw materials will be crushed and ground, then they are separated and concentrated to separate the waste ingredients out. 卖点、特色句]
