Plating Bath Filtration: Filter Rating and Particle Contamination Plating baths are filtered continuously, and the reason is that particles do not stay in the solution. A speck of dust, a fragment of anode bag, a chip of dried plating salt or a flake of resist all end up deposited on…

Solder Wave Height and Contact Time Control Wave height is the depth of solder that stands above the nozzle lip as the board passes over it. Set correctly, the wave touches the underside of the board across its full width and the board floats on the crest with a small,…

Solder Paste Powder Size Selection: Type 3 to Type 6 Solder paste is a suspension of alloy spheres in flux, and the size of those spheres is specified as a type number with a corresponding particle range. The choice looks like a detail, but it decides how the paste behaves…

Lamination Separator Plates: 6 Rules for a Clean Press Book Lamination separator plates sit between the tooling plate and the panel, and they quietly determine whether a press cycle produces a smooth surface or a marked one. They distribute pressure, carry heat into the stack and keep resin flash from…

Solder Mask Curtain Coating: 6 Settings for Even Thickness Solder mask curtain coating covers one or both panel faces with a falling film of ink, which makes it fast and material efficient compared with screen printing. It also concentrates a great many variables into a single pass. If the curtain…

Plating Jig Maintenance: 6 Checks for Even Current Transfer Plating jig maintenance is the difference between a rack that plates evenly and one that produces panels with thin copper in one area and burns in another. The jig carries current from the busbar to the panel, and every contact in…

PCB Etch Factor 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 etch factor timing gives you a practical advantage when…

Rinse Water Temperature Control: 6 Checks for Cleaner Panels Rinse water temperature is the parameter that decides how much chemistry leaves the panel and how much stays on it. Cold water removes salts slowly, warm water dissolves and carries them away far more effectively, and water that is too hot…

PCB Etch Factor Handover: Passing It On 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 Etch Factor Specification: Writing It Down Precisely 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…
