Hot Air Solder Leveling Process for Dual-Layer Circuit Boards
Double-sided hot air solder leveling (HASL) PCB is a type of printed circuit board where both sides of the substrate are treated with the hot air solder leveling process, featuring practical performance and wide adaptability. Its core characteristics are as follows: The surface treatment involves uniformly covering the copper surface with molten tin-lead alloy (or lead-free tin alloy), which is then leveled by hot air to form a flat, bright tin layer with moderate thickness and strong adhesion. This process endows the board with excellent solderability, ensuring good wetting of the solder during component welding, reducing the risk of cold solder joints. Moreover, the tin layer allows for multiple rework soldering, making it suitable for mass assembly and later maintenance needs. Meanwhile, the tin layer has certain oxidation resistance and protective capabilities, which can protect the copper surface from environmental corrosion, extend the storage and service life of the board, and is particularly suitable for general industrial environments such as humid and dusty conditions.
Core Characteristics:
| Feature | Description |
| Layer Structure | Conductive copper layers on both top and bottom sides of the insulating substrate |
| Interconnection | Plated through-holes (vias) connect circuits between the two layers |
| Wiring Capacity | Double-sided routing enables higher wiring density and complex circuit layouts |

FAQ:
1.Q:How many layers can your circuit boards provide?
A:We typically provide 1-30 layer boards, and in special cases, we can stack more layers.
2. Q:Do your circuit boards support customization?
A:Yes, we support customized designs. You can send us your Gerber files and BOM list, and we will provide you with an accurate quote based on the information and market conditions.
3. Q:What do Gerber files typically contain?
A:Normally Gerber files Include:PCB Types,Product thickness, Ink color, Surface treatment process and If SMT processing is required, component BOM and tag drawing are also required.
4. Q:What is your minimum order quantity for PCB boards?
A:Our minimum order quantity is 1 piece(5 square meters),the larger the quantity, the bigger the discount.
5. Q:Do you have relevant certification certificates to support this?
A:We hold numerous important certifications, including ISO, UL, CE, and RoHS. All products undergo rigorous quality testing.
6. Q:What payment method do you usually use?
A:For small orders, samples, or urgent payments, we accept Western Union. For large orders, we recommend T/T, which ensures the safety of both parties.
