PCB Copper Thickness and Current: How Much to Use Copper weight and current capacity are linked by resistance and heat. A track carries current, and every ohm of resistance turns some of that current into heat. The copper thickness sets the cross section, the cross section sets the resistance, and…

SMT Process From Printing to Test: Parameters and Defects The surface mount process is a chain of short operations, each with its own parameters, and the quality of the finished assembly is decided by how well they agree with one another. A solder joint that looks wrong is rarely the…

PCB Solder Mask Colour and Contrast: Choosing How the Board Looks 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.…

PCB Two Part Adhesive Mixing: Mixing Before Use 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 two part adhesive mixing gives you a practical advantage…

PCB Thermal Cure of Adhesives: Curing With Heat 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 thermal cure of adhesives from the perspective of a PCBA factory…

PCB Ultraviolet Cure of Coatings: Curing With Light 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 ultraviolet cure of coatings gives you a practical advantage…

PCB Conformal Coating Spray Versus Dip: Two Ways to Coat 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…

PCB Adhesive Selection for Staking: Holding a Part Down 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 adhesive selection for staking from the perspective of a PCBA…

PCB Gap Filler Dispensing: Putting It in the Gap 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…

PCB Thermal Interface Application: Applying the Material 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 thermal interface application from the perspective of a PCBA factory floor, covering…
