Company Advantages
1. A-TECH hard gold pcb is recommended only after surviving the stringent tests in our laboratory. They include appearance quality, workmanship, colorfastness, size & weight, smell, and resilience. Its solderable surface is protected from the oxidation
2. A-TECH CIRCUITS Co., Ltd. keep well informed about hasl pcb technical developments, new application and new products in the field. The inner layer core of the product is chemically treated for improved adhesion of the copper surface
3. Our professional team ensures that the product is flawless and trouble-free before leaving the factory. It is 100% produced in accordance with IPC-6012 & IPC-A-600F standards


Immersion Silver, it’s also known as Immersion Ag, it’s produced by the selective displacement of the copper atoms by silver atoms on the exposed copper surface. As an improvement on HASL with more flat surface, the cost of Immersion Ag is more expensive than HASL but less expensive than Immersion Gold.

Immersion Ag is a RoHS compliant finish, and it’s compatible with surface mount, BGA and through hole components. The typical thickness of Imm Ag is 0.1-0.3um and the shelf life is 6-12 months.



The advantages of Immersion Silver

● Absolutely flat
● Good for fine pitch and SMD
● Good for press fit connector’s capability
● Excellent solderability
● Multiple heat cycles during assembly process
● It’s reworkable



The disadvantages of Immersion Silver

● Very sensitive to handling / tarnishing / cosmetic concerns – gloves must be used
● Short operating window between assembly stages
● Not recommended to use peelable masks
● Special packaging required – if packaged opened and not all boards used, it must be resealed quickly
● Reduced supply chain options to support this surface finish



A-TECH offers the surface finish of immersion silver, since this finish is much more sensitive in manufacturing and it’s more susceptible to temperature and humidity than other finishes, we use special operation standards and higher level of packing standards to ensure excellent appearance of immersion Ag.




Company Features
1. We expect no complaints of hasl pcb from our customers.
2. Our company's commitment to reducing the carbon footprint is unwavering. We will work hard to reduce indirect greenhouse gas emissions through the reduction of electrical consumption.
A-TECH hasl pcb is produced under strict scrutinization. It is checked for its material ingredients as well as material extraction methods to guarantee its quality. Its neck is sealed through double TIG welding, ensuring excellent airtightness
The production of A-TECH hasl pcb 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. It meets international standards and passes the tests of SGS
High-tech processing equipment is used in the production of A-TECH hard gold pcb. It is done under the detritus equipment, grinding equipment, as well as sand-making equipment, which can guarantee high purity and fineness. Its handhole is well deburred for improved safety
The raw materials of A-TECH hard gold 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. It helps keep constant temperature which will not ruin beer flavour
A-TECH hasl 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]
