Revision B of the IPC-4101 specification was released in June 2006.The committee responsible for this specification worked hard to add material specification sheets that included some of the properties discussed in Chaps. 10 and 11 in regards to lead-free assembly. Table 11.6 summarizes some of the new specification sheets that include properties such as decomposition temperature, z-axis expansion, and time-to-delamination values.

It is important to understand that these requirements apply to laminate materials and not the PCBs manufactured from them. Furthermore, the time-to-delamination requirements are for unclad samples. All of the variables outlined in Section 11.2 regarding printed circuit fabrication and assembly must also be considered when specifying a material. It is also critical to understand that no one property will guarantee success in lead-free applications. When faced with uncertainty, the natural tendency is to overspecify each property. Not only could this cause the user to pay too much for a material, but overspecifying specific properties can also lead to functional problems. These problems can be the result of the interaction between advanced materials and the PCB fabrication processes required to manufacture reliable PCBs. Take decomposition temperature, Td, as an example. Section 10.2.2 discussed the importance of Td with respect to lead-free assembly compatibility. Although the 5 percent level of decomposition has been the standard reported value, the point was made that this is a very high level of decomposition from the standpoint of PCB reliability. It is important to understand when decomposition begins and how close this temperature is to actual assembly and rework process temperatures. A material with a reported Td, based on the 5 percent level, of 325 C may perform just as reliably, or even more reliably, than a material with a 5 percent Td value of 340 C, depending on what the decomposition characteristics are in the lead-free assembly and rework temperature ranges. Specifying materials with significantly higher Td values may not improve reliability, and may potentially add cost and difficulty to the manufacturing process if the higher Td material is more difficult to process for example, if the lamination times are longer, or if it is harder to drill or score. Although future specification sheets may include Td values based on lower levels of decomposition, it is very important to understand these properties in some detail and specify the appropriate material for a given application. In summary, experience to date indicates that specification sheets 99 and 124 are suitable for a very broad range of applications. For lead-free applications, the user should consider these as the baseline. Simple low-technology PCBs or those that do not have stringent longterm reliability requirements may successfully use the materials covered by sheets 101 or 121, whereas very advanced products may need more stringent requirements, such as those covered by sheets 126 and 129. Finally, always check for the most recent revision of IPC4101, as new specification sheets will be added as more experience is gained and data are gathered.
