Solution Development from Requirement Definition to Mass Production A solution development project begins with a requirement and ends with a product that can be manufactured, and the distance between those two points is filled with decisions that are much cheaper to take early than late. This introduction describes the route…
PCB Fabrication Capability: Two to Thirty Layers PCB fabrication covers a wider range than most buyers expect when they first place an order. The same shop can cut a two layer prototype on a Friday and laminate a thirty layer backplane over the following fortnight, and the reason those two…
PCB Flex Coverlay Selection: Covering a Flexible Circuit 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 Design Service: From Schematic Capture to a Released Gerber Set A PCB design service is judged on two things that are easy to separate and hard to confuse: whether the resulting board works, and whether the data that leaves the door can be manufactured without a further round of…
PCB Specialty Substrate Selection: From Design to Repeatable Production 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 Copper Foil Type Selection: What Buyers and Engineers Should Check 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 Prepreg Resin Content: What Buyers and Engineers Should Check 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 prepreg resin content from the perspective of a PCBA…
SMT Prototype Builds: Data Intake, Stencil and First Article Release A prototype order is small by definition, and that is exactly why it deserves the full process. The purpose of an SMT prototype build is not merely to produce a board that powers up. It is to verify that the…
BGA and QFN Solder Joint Control with X-ray Inspection Ball grid array and quad flat no-lead packages are popular because they fit a large number of connections or a good thermal path into a small footprint. The price of that density is that the main solder joints sit beneath the…
PCB CTE Mismatch in Assembly: A Practical Manufacturing Guide 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…
