Page 3: Objective
This document provides general guidelines for Printed Circuit Board (PCB) design and assembly of Murata's SCC1000 series components. It should be emphasized that this document serves only as a design guideline to help develop the optimal assembly conditions. It is essential that users also use their own manufacturing practices and experience to be able to fulfill the needs of varying end- use applications. -

Figure 6. PCB pad lay-out for the DIL-32. Murata's DIL packages can be soldered on commonly used substrates, e.g. FR-4, ceramic etc. The pad metallization should be solder wettable in order to assure good quality solder joints. For fine pitch assembly, the quality of plating is important. -
Page 8: Stencil
Pin #1 is indexed by a dot mark on the component lid as illustrated in Figure 4. In the case of double sided SMT assembly, it should be noted that Murata's components are relatively heavy and they should be glued on the PCB if they are located on the bottom side of the PCB during the second solder reflow process. -
Page 9: Reflow Soldering
If washing process is done after the soldering process, it must be noted that ultrasonic agitation wash after reflow is not allowed for Murata's DIL packaged MEMS components. As mentioned before (section 5.2) a no-clean paste is recommended. -

Page 12: Precautions
As a general guideline, lower the viscosity or higher the modulus of coating, higher the probability of adverse effects on sensor component. Murata Electronics Oy Assembly Instructions for Murata's SCC1000 series TN82 www.murata.com Rev. 2.0... -
Page 13: Vacuum Level
PCB pad and through that the heat should be conducted to the tin wire and component lead. Murata has used 315ºC setting temperature for component soldering. The temperature on the tip of the tool is 270...275ºC. -
Page 14: Method B: Soldering By Applying Solder Paste And Then Using Reflow Heating Or Soldering Iron
Rework Guidelines If it becomes necessary to rework a SCC1000 series component, the preferred way to remove the component is by hot air. Use of a hot air rework station with a vacuum chuck, is the preferred method. -

Same temperature is used both for Pb-free and SnPb-solder joints, even though SnPb solders melt already below 200ºC. Some temperature adjustment might be needed. Especially if tool head is old and 'dirty' temperature needs to be increased.
