Of course, the road to shipping a product is a long one, and requires a unique set of skills quite distinct from those required to build the initial prototype. In developing a product for Airsoft use, <a href=\"http:\/\/baldgreg.com\/projects\/sigma-mosfet-production-test-rig\/\" target=\"_blank\" rel=\"noopener noreferrer\">[bald greg] realized that a testing rig would be key to ensuring their hundreds of units left the building in working condition.<\/a><\/p>\n<p>When shipping units in the hundreds rather than thousands, keeping overheads low is key to maintain a sustainable profit margin on each unit sold. Thus, [bald greg] built a rig that would allow for effective testing of devices rather than breaking the bank. The rig also handles programming, saving the cost of purchasing pre-programmed microcontrollers from the manufacturer. A Raspberry Pi runs the show, using its GPIO pins to program boards and saving test results and serial numbers for later reference. A bed of nails fixture is used to connect to each individual board. Additionally, to test each board as realistically as possible, hardware mimicking a real Airsoft electric pistol is used to properly load the hardware.<\/p>\n<p>[bald greg]&#8217;s work is a great example of approaching QC on a budget, and we suspect he&#8217;ll sleep soundly knowing the boards in the mail are going to work first time. <a href=\"https:\/\/hackaday.com\/2019\/02\/09\/test-pcbs-on-a-bed-of-nails\/\">We&#8217;ve seen others take similar approaches, too.<\/a> If you&#8217;re working on your own production testing rig, <a href=\"http:\/\/hackaday.com\/submit-a-tip\">be sure to let us know!<\/a><\/p>\n<p><span id=\"more-432038\"><\/span><\/p>\n<blockquote class=\"wp-embedded-content\" data-secret=\"StOzj6jq0G\">\n<p><a href=\"http:\/\/baldgreg.com\/projects\/sigma-mosfet-production-test-rig\/\" target=\"_blank\" rel=\"noopener noreferrer\">SIGMA MOSFET- Production test rig<\/a><\/p>\n<\/blockquote>\n<p><iframe class=\"wp-embedded-content lazyload\" sandbox=\"allow-scripts\" security=\"restricted\" title=\"&#8220;SIGMA MOSFET- Production test rig&#8221; &#8212; bald.greg\" data-src=\"http:\/\/baldgreg.com\/projects\/sigma-mosfet-production-test-rig\/embed\/#?secret=StOzj6jq0G\" data-secret=\"StOzj6jq0G\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" data-load-mode=\"0\"><\/iframe><\/p>\n<p>source <a href=\"https:\/\/hackaday.com\/2020\/09\/20\/a-budget-testing-rig-for-low-volume-production\/\">https:\/\/hackaday.com\/2020\/09\/20\/a-budget-testing-rig-for-low-volume-production\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>It&#8217;s not unheard of for those who tinker in the land of electronics to suddenly find themselves with a project on their hands and potential customers clamoring at the door.
