How to avoid the PCB tombstone in PCBA process

The PCB tombstone , also known as the Manhattan or drawbridge effect, is a chip (passive) component assembly defect situation. The cause of the PCB tombstone is that the melting time of the solder paste at both ends of the part is inconsistent, resulting in uneven force at both ends of the chip component, which is relatively light in mass and will cause one side to roll up under the action of stress.
