Wave Solder Chip Wave Setup: Turbulence, Bridging and Thermal Load The chip wave, also called the turbulent wave, is the small wave that runs ahead of the main wave to wet the surface and drive flux gases away from the joints. Its settings decide whether the board bridges on fine…

PCB Board Storage Selection: Choosing What Fits Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years. This article explains PCB…

PCB Board Storage Control: Holding It Steady Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years. This article explains PCB…

PCB Board Storage Improvement: Getting Better Each Lot Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years. This article explains…

Depaneling Strain Measurement: Gauge Placement, Limits and Data Depaneling is the last mechanical operation a board sees, and it is the one most likely to crack a solder joint that passed every inspection before it. Strain measurement turns that risk into a number, which is the only way to compare…

Dispensing Valve Maintenance: Needle Wear, Dots and Volumetric Control A dispensing valve is judged by the material it places, cycle after cycle, over a shift and over a month. The variables that decide that are the condition of the needle, the stability of the pressure or the screw, and the…

PCB Board Storage Traceability: Following One Board Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for years. This article explains PCB…

PCB Board Storage Environment: Where It Happens 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 board storage environment gives you a practical advantage when you…

PCB Board Storage Timing: How Long It Takes 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 board storage timing gives you a practical advantage when…

Solder Mask Plugging Depth Control: Via Fill and Inspection Methods Solder mask plugging is a via fill operation in which a screened paste is printed into the hole so that it is closed before assembly. The requirement is not simply that the hole is closed; it is that the plug…
