Are there any requirements for attention during the processing of half-hole pcb?
PCB half-hole boards are widely used in practical applications, but there are also some attention requirements in their processing. This article explains these issues in detail, including the design, processing and testing of half-hole boards, to help readers more clearly understand the adverse consequences during the processing process.
1. Design principles of half-hole board
Issues that need to be paid attention to when designing half-hole boards include plate thickness, board edge conditions, opening matching and scratches, etc. This article explains these issues one by one to ensure the rationality and stability of the half-hole plate design.
2. Things to note when processing half-hole boards
Half-hole boards processing involves drilling, milling, welding and other links. When drilling, you need to pay attention to aperture, plate slack, drill core offset and other issues; when milling slots, you need to pay attention to route planning, cutting allowance and other issues; when welding, you need to master skills such as pad size, ringing and welding slag.
3. Methods and standards for half-well board testing
After half-hole board processing is completed, strict testing is required to ensure its quality and stability. Commonly used inspection methods include visual inspection, high-power microscope inspection, sheet metal machine inspection, etc.; commonly used standards include IPC-6012, MIL-P-50884, etc.
4. Storage and transportation of half-well boards
Half-well boards are susceptible to mechanical damage, moisture oxygen corrosion, etc. during storage and transportation. This article provides an in-depth analysis of these issues and provides some effective storage and transportation tips to avoid undesirable half-well plates during transportation.
PCB half-hole boards design and processing requires some necessary skills and experience, and its inspection and storage also require attention to some specific details. Only by completing these details can the half-hole board have high stability and reliability in practical applications.
