As per my reading there are few approaches like first one is removing all the component smearing the mas over the board, second one with this mass artificially increase the stiffness ( But i don&#8217;t how much it should be) then last one is keeping all the major components on pcb with assigning a material properties, I need to use last one approach where i will keep major component on PCB but the issue here is what properties should i consider of these particular PCB Components , As we know PCB components like BGA or any ICs are made of different material so how do we actually assign material for these?<\/p>\n<p>Overall my question is regarding what properties we should assign to pcb board components , shall we assign property of package material or what&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-310353","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["284329","13632"],"_bbp_author_ip":["96.7.218.223"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["462"],"_edit_lock":["1696656402:217291"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["310353"],"_bbp_forum_id":["27791"],"_bbp_engagement":["13632","284329"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["310483"],"_bbp_last_active_id":["310483"],"_bbp_last_active_time":["2023-10-07 07:04:36"]},"test":"balaji-bpcoreel-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/310353","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/310353\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=310353"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
