Transformers of known PCB content (polychlorinated biphenyl) over 50 ppm (parts per million) must be handled and disposed of in a manner that adheres to a strict code of Federal … If you want to get your product out the door quickly, this may not be your best choice. The last thing any designer wants is to discover last-minute that their product is faulty. If a board fails, it is known as an infant mortality. This type of inspection … They put a certain amount of pressure on the connection to make sure it stays intact. A functional circuit test is exactly what it sounds like — it tests the function of the circuit.  If it’s going into a PCI interface, or if it’s a modem, electricity or communication will be applied in all the right places. }, What Does the IPC 6011 Standard Mean to PCB Manufacturing? ICT can be faster and less error-prone than flying probe testing, so you might find the extra cost is worth it. During the testing process, several components of PCBs are analyzed in detail, including: 1. NOTE: One or more of these methods may lack the sensitivity required to detect total PCBs … If few or no defects are found, it's possible to reduce the testing limit after a shorter period to avoid over-stressing your PCBs. We analyze for single Aroclors such as Aroclor 1260, Aroclor 1254, or Aroclor 1016 or for a list of PCBs like those in EPA 608.3 or SW846 8081/8082.
