SPI Testing Principle and Application

图片
The principle of SPI testing is commonly utilized in SMT assembly to verify the accuracy of the solder paste application on the pads. SPI testing is beneficial for identifying various issues in solder paste application, such as: •   Solder paste voids : indicating incomplete filling of the pad, potentially leading to weak solder joints. •   Solder paste bridging : where the solder paste forms unintended connections between pads, possibly causing short circuits. •   Solder paste offset : a situation where the solder paste is not correctly aligned on the pad, potentially resulting in subpar solder connections. Different methods of SPI testing are utilized, including   optical SPI inspection , X-ray SPI inspection , and   3D SPI inspection . Optical SPI inspection   involves using a camera to examine the solder paste's shape and size and generate a three-dimensional image by capturing an image of the solder paste on the pad.

A Complete Guide to Rigid Flex PCB

图片
  A rigid flex PCB is a circuit board that combines rigid sections (typically made from FR4) and flexible layers (often polyimide). These layers are laminated into a single structure, so there are no connectors between them, no soldered jumpers, no cabling.It acts like one board, even though parts of it fold. This makes rigid flex rigid PCBs perfect for 3D designs. Need to wrap a circuit around a hinge? Done. Need a board that folds during installation but stays rigid once placed? That’s what flexible rigid PCBs are built for. In a PCB rigid flex design, the flex portions connect the rigid sections internally. These flexible sections often experience bending, folding, and even constant movement. That’s why the material and stack-up matter so much. If you’ve heard terms like “rigid flex printed circuit boards” or “flex-rigid PCBs,” they all mean the same thing: a board built to bend where it needs to, and hold firm everywhere else. Let’s recap what makes a rigid flex PCB the go-to s...

Flexible Circuit Board with Reinforcement Ribs

 As a final step in manufacturing, stiffeners can be added to flex-circuits. They are applied using a pressure-sensitive adhesive or thermoset adhesive. Pressure-sensitive adhesives are the most cost-effective. Thermosetting adhesives (traditional prepregs for PCBs) require that the flexible PCB be placed into the laminator in order to apply heat and pressure to cure the adhesive. When specifying PCB stiffeners for use with plated-through-hole components, make sure that the stiffener is on the same side as the board you will insert the component into. This will allow the pads to be used. It is important to align the holes on the stiffener with the through-holes plated on the PCB in these applications to allow component leads to easily pass through the holes. Customers must work closely with their flexible PCB manufacturers to determine if the adhesive system and registration method are adequate to meet customer needs.

What is a Cold Solder Joint and How to Fix or Prevent It

  PCB solder joints are typically small, and this is especially true as board sizes continue to shrink. Therefore, visual aids such as a magnifying glass or spotlight are often required to inspect them clearly. Checking the color of the joints is the first stage in this visual inspection.  This is significant since a well-formed solder joint usually looks dull. Next, the shape of the solder joint is inspected. If the joint is distorted or lacks the expected concave profile, insufficient heating likely prevented the solder alloy from fully melting. Consequently, this can lead to increased electrical resistance, which heats the joint—potentially causing it to crack and eventually detach from the board. Subsequently, use a torch and magnifying glass to check for light penetration through the joints. If light passes through a joint, it indicates poor bonding, requiring rework. Finally, tilt the board to inspect for joints that are partially loose from the board’s substrate. The ...
