Maybe I&#8217;ll add a flux-off stage to the process&#8230; probably not on these alpha boards though. \u00a0I&#8217;m still waiting on parts!! \u00a0Hopefully they&#8217;ll be in soon, so I can finish the kits.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Just finished Reflowing 7 Ultimate Arduino Programmer Boards. \u00a0They turned out pretty good, except for a few minor issues. \u00a0I had to change the critical temperature to 180-190C and extend the soak time at the critical temperature. \u00a0I had to bake these boards twice, so&hellip;&nbsp;<a href=\"https:\/\/www.kevindarrah.com\/?p=1576\" class=\"\" rel=\"bookmark\">Read More &raquo;<span class=\"screen-reader-text\">First Batch of Programmer Boards<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"ngg_post_thumbnail":0,"footnotes":""},"categories":[100],"tags":[80,97,98,96,95],"class_list":["post-1576","post","type-post","status-publish","format-standard","hentry","category-proto","tag-arduino","tag-board","tag-programmer","tag-prototype","tag-ultimate"],"_links":{"self":[{"href":"https:\/\/www.kevindarrah.com\/index.php?rest_route=\/wp\/v2\/posts\/1576","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.kevindarrah.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.kevindarrah.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.kevindarrah.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.kevindarrah.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1576"}],"version-history":[{"count":2,"href":"https:\/\/www.kevindarrah.com\/index.php?rest_route=\/wp\/v2\/posts\/1576\/revisions"}],"predecessor-version":[{"id":1657,"href":"https:\/\/www.kevindarrah.com\/index.php?rest_route=\/wp\/v2\/posts\/1576\/revisions\/1657"}],"wp:attachment":[{"href":"https:\/\/www.kevindarrah.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1576"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.kevindarrah.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1576"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.kevindarrah.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1576"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
