Lead-free soldering defects can be prevented by coordinating pad design, component finish, solder paste, stencil printing, placement, reflow profile, and board cleanliness. Higher process temperatures make thermal control and material compatibility especially important.
Learn more →Wire bond quality is strongly affected by bond force, ultrasonic energy, bonding time, temperature, capillary condition, wire properties, and pad cleanliness. These factors interact, so stable results require a qualified process window.
Learn more →Probe-card cleaning frequency should be based on contact resistance, touchdown count, pad metallurgy, debris accumulation, and retest trends rather than a fixed universal interval. Cleaning too late increases false failures, while excessive cleaning can shorten probe life.
Learn more →Plasma treatment improves adhesion by removing trace contamination and increasing surface energy through controlled activation. Better wetting allows adhesives, coatings, and encapsulants to spread more evenly and form stronger interfaces.
Learn more →Plasma cleaning is recommended when organic residue, weak boundary layers, or poor surface wettability may affect bonding, coating, molding, or adhesion. It is commonly used before die attach, wire bonding, underfill, encapsulation, and other critical assembly steps.
Learn more →Dicing blades are precision tools and should be protected from impact, bending, moisture, dust, and chemical contamination. Correct storage and handling preserve blade geometry and reduce unexpected breakage during setup.
Learn more →Premature blade wear is usually caused by an unsuitable blade specification, excessive feed load, poor cooling, incorrect dressing, spindle vibration, or contamination at the flange. Wear should be evaluated together with cut quality and spindle load.
Learn more →Wafer dicing chipping can be reduced by matching the blade, spindle speed, feed rate, cut depth, coolant flow, and mounting method to the wafer material and thickness. Both front-side and backside chipping should be measured because they can have different root causes.
