Using appropriate spray pressures to reach under low-clearance components without causing damage.
A critical takeaway from the IPC-CH-65 guidelines is the debunking of the "no-clean" myth. While no-clean fluxes are designed to leave benign residues, factors such as high component density, low under-clearance, and harsh operating environments can still lead to field failures if these residues are not managed. IPC-CH-65B provides the technical framework to decide whether cleaning is necessary for a specific application. Integration with Other IPC Standards
IPC-CH-65 is typically used alongside other core IPC standards to create a complete manufacturing quality strategy: ipc-ch-65 pdf
