Prototype Lead Time: Where the Days Actually Go A prototype schedule is usually quoted as a single number of days, and the number is treated as a property of the supplier. In practice it is the sum of several steps, each with its own floor, and knowing which of them…

PCB Final Assembly Torque Control: Tightening Without Breaking 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 final assembly torque control gives you a practical advantage…

Small Orders Deserve Full Process Control There is a particular failure in batch assembly that rarely appears on a formal list: the board that would have been built correctly if the order had been large. Where a supplier’s schedule is organised around volume, a small quantity can be treated as…

Ultra-Small Passives: Building Boards With 008004 Parts Each generation of portable and wearable electronics moves a step further in the same direction: less space, less thickness, more function. The component families follow, and the smallest passives now in volume production are around two tenths of a millimetre in length and…

PCB Box Build Process: Putting It in the Case 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 Sub Assembly Testing: Testing Before the Final Build 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 sub assembly testing from the perspective of a PCBA factory…

PCB Module Soldering Onto A Carrier: Mounting a Module 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 module soldering onto a carrier gives you a…

PCB Board to Board Spacing Design: Keeping Two Boards Apart 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…

Point Count: How Placement Work Is Measured Placement is usually priced by counting. The coordinate file contains a position for every device, the positions are totalled, and the total is multiplied by a rate that depends on the class of work. It is a transparent method and it has the…

PCB Mezzanine Connector Design: Board on 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…
