Component Bake Schedules and Floor Life A component that has absorbed moisture and is heated quickly can crack internally, and the crack is invisible from outside. The bake is the operation that removes the moisture before the heat arrives, and its schedule is set by the package rather than by…

Assembly DFM Review Agenda A manufacturability review is the last cheap opportunity to change a design. After the layout is released, a change costs a revision, a new stencil, a new program and possibly a scrapped panel; before release, it costs a conversation. The difference between a review that finds…

Solder Paste Open Time and Work Life on the Line Solder paste changes from the moment the jar is opened. The solvent evaporates, the flux chemistry reacts with the air and the viscosity rises, so a paste that printed correctly in the morning behaves differently in the afternoon. Open time…

PCB Oven Zone Improvement: A Factory-Floor Review Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB oven zone improvement gives you a practical advantage when you…

PCB Oven Zone Selection: A Factory-Floor Review Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB oven zone selection from the perspective of a PCBA factory floor, covering…

Paste Kneading and Print Stability Over a Shift Solder paste is a suspension, and a suspension separates. Kneading is the operation that restores the mixed state before printing, and the stability of the print over a shift depends on it being done consistently rather than quickly. What Happens Without Kneading…

Moisture Sensitivity Level and Floor Life Control A plastic package absorbs moisture from the air. When it is heated to reflow temperature the moisture turns to steam, and the pressure can crack the package from the inside, delaminate the die attach or lift the wire bonds. The damage is called…

PCB Oven Zone Problems: From Design to Repeatable Production Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB oven zone problems gives you a practical advantage…

PCB Conveyor Review: A Second Look at Line Control Most buyers judge a conveyor by its frame and its price. That view misses the real job it does. A conveyor sets board position, transfer timing and thermal stability between every station on the line. When those three factors drift, placement…

PCB Oven Zone Checklist: What Buyers and Engineers Should Check Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB oven zone checklist gives you a practical…
