Residues act as a barrier to conformal coatings, causing delamination, blistering, and exposing the underlying circuitry to harsh environments.

Elias was a restorer of dead technology. In the back room of his cluttered shop in downtown Seoul, surrounded by humming oscilloscopes and stacks of vintage CRT monitors, he worked on a peculiar relic he had fished out of a government surplus auction.
The IPC-CH-65 PDF serves as a vital resource for anyone involved in the PCB assembly process. By adhering to the guidelines and standards set forth in this document, manufacturers can ensure that their products meet the highest levels of quality and reliability. Whether you're a seasoned professional or just starting out in the field, understanding and applying the principles outlined in IPC-CH-65 is crucial for success.
Contaminants like flux activators, plating chemicals, and fingerprint oils can lead to electrochemical migration, corrosion, and leakage currents. While many manufacturers use "no-clean" fluxes, IPC-CH-65 clarifies that even these can leave problematic residues, especially with high-heat lead-free reflow processes that change the character of the remaining residue.

Oils, greases, waxes, and fingerprint oils. These can act as insulators, preventing proper solder bonding or coating adhesion.
The document is structured to cover the entire cleaning cycle, from PCB fabrication to final assembly cleaning. 1. Types of Contaminants

Ionic contaminants combine with ambient moisture to create dendritic growths. These metal whiskers bridge trace gaps, causing short circuits.
The , is the industry-standard document designed to guide engineers, technicians, and quality control professionals through the complexities of cleaning processes.
