Immersion gold should be used to avoid tin blast holes.
HASL is also called hot air leveling (HSAL). Its processing method is to immerse the board vertically down through the guide rail into the liquid high-temperature tin liquid, and then lift it up, and use strong hot air to blow the tin liquid on the surface of the slot hole plate. If the tin hole is too large (round hole or oval hole), the copper surface of the hole wall will sometimes fall off from the base material, which will cause part or all of the copper surface of the hole wall to fall off , causing an open circuit.

Why Tolerance Analysis Is Key to Reliable and Cost-Effective PCB Production
Key Takeaways Tolerance analysis bridges CAD perfection and manufacturing variations to ensure reliable PCB assembly. Focus on critical areas: annular rings, hole tolerances, trace/space, layer registration, and solder mask alignment. Apply Worst-Case, RSS, or Monte Carlo methods for effective tolerance stack-up. Proper analysis boosts yield, cuts respins and costs — start with JLCPCB’s DFM review. Have you ever sent a board to fabrication, which appeared flawless on the computer screen, but then foun......
The Ultimate Guide to PCB Panelization: Tools and Techniques
Printed circuit boards (PCBs) are the backbone of modern electronics. One critical aspect of PCB manufacturing is panelization — the process of arranging multiple PCBs onto a single larger panel for efficient manufacturing and assembly. This technique allows multiple boards to be processed simultaneously, significantly reducing costs and improving production efficiency. In this article, we will provide a comprehensive guide to PCB panelization, covering the tools and techniques required for successful......
Castellated PCBs: Introduction and Design Requirements
With the rapid development of electronic technology, electronic products are moving towards miniaturization, portability, multi-functionality, high integration, and high reliability.Consequently, printed circuit boards (PCBs) are frequently designed to integrate pre-existing, off-the-shelf modules. For example, IoT Bluetooth modules or NB-IoT modules, which are indispensable communication modules, can be soldered onto PCBs just like chips. These carrier boards are characterized by their small size and......
Copper Balancing in PCBs: Achieving Optimal Performance and High Yields with JLCPCB
Key Takeaways Copper balancing strategically distributes copper across PCB layers to create uniform density, preventing warpage, uneven plating, inconsistent etching, and signal integrity issues. The ideal copper density target sits within the 40%–60% golden ratio, with mirrored layers maintaining density variation within 15%–20% per IPC-6012 standards. Copper thieving (dot patterns or crosshatch meshes) equalizes current density during electroplating without introducing parasitic capacitance on spars......
PCB Design : How to Resolve Short Circuit Defects Caused by HASL
Key Takeaways In high-density PCB designs, HASL frequently causes solder bridging and short circuits due to its uneven surface and molten solder flow, especially on fine-pitch and dense traces. The most effective solution is to switch to ENIG (Electroless Nickel Immersion Gold), which provides superior planarity, significantly reduces bridging risks, and improves assembly yield. By selecting ENIG for dense layouts, optimizing solder mask design, and running DFM checks, designers can effectively elimin......
