dryjointed
Dryjointed is an adjective used in electronics to describe a solder joint that has formed improperly, resulting in a poor or nonexistent electrical connection. A dry joint, and by extension a board described as dryjointed, typically shows inadequate wetting of the pad and component lead, leaving a dull, cracked, or uneven fillet. This condition can cause intermittent connectivity or complete loss of signal.
Causes of dry joints include insufficient heat during soldering, oxidation on pads or leads, and residues from
Symptoms and impact vary from intermittent faults to permanent open circuits. Visually, joints may appear grey
Diagnosis typically involves visual inspection, continuity testing, and resistance measurements. In complex cases, especially with densely
Remedies focus on proper rework: remove the defective joint, thoroughly clean the area, and reflow with appropriate
