\"\"<\/a> For those of us in the heat sink, heat sink attach and thermal design space heat sink attach is a big bugaboo.\u00c2\u00a0 There are many options to choose from for sure and each has it’s own pluses and minuses.\u00c2\u00a0\u00c2\u00a0 The key is to choose the right attachment method given the thermal requirements, application and cost.\u00c2\u00a0 Many times engineers will just default to tape and when in doubt will choose epoxy.\u00c2\u00a0\u00c2\u00a0 At ATS we’ve seen the use of thermal epoxy so much it makes us weep!\u00c2\u00a0\u00c2\u00a0 Epoxy seems like the answer to make sure a heat sink stays on during shock and vibe testing.\u00c2\u00a0 The use of the epoxy is subject to many variables.\u00c2\u00a0 There are other options, two of which just came onto the market.<\/p>\n

Alpha Novatek has just released it’s Quick Set family of Heat Sinks<\/a>.\u00c2\u00a0 Here’s a description from their press release<\/p>\n

Electronic components have become faster and more compact, generating more heat and increasing thermal densities. This has led to the use of heat sinks of increased size and mass. One of the biggest challenges for thermal\/mechanical engineers is mechanically mounting larger heat sinks while minimizing the amount board real estate used by the attachment mechanism. Generating sufficient attachment force is also critical with regards to mechanical security and proper performance of thermal interface materials.<\/p>\n

Alpha’s new Quick Set series heat sinks have been designed to address both issues, providing secure and reliable attachment while requiring the absolute minimum of board real estate.<\/p><\/blockquote>\n

In a nutshell, Quick Set requires a small mounting pins be placed onto a PCB. Mounting pins only require 1.8mm[.071″] diameter holes in the PCB.\u00c2\u00a0 Then a heat sink can be clipped on creating a secure attachment that uses minimum space.\u00c2\u00a0\u00c2\u00a0 It also appears it can handle oversize heat sinks too, a real boon with large footprint semiconductors.\u00c2\u00a0 More information and photos are on the official announcement on Alpha Novatech’s web site at this link here<\/a>.<\/p>\n

For ATS’s part, we’ve approached this same problem of heat sink attachment by way of clip technology.\u00c2\u00a0\u00c2\u00a0 Our latest is superGRIP, an attach technology which puts a clip around the semiconductor and allows spring to hold the heat sink down.\u00c2\u00a0 Our studies and those of our major customers indicate superGRIP does not put strain on a BGA.\u00c2\u00a0\u00c2\u00a0 superGRIP’s differentiator over Alpha’s Quick Set is that superGRIP does not require any holes in an electronics board PCB.\u00c2\u00a0\u00c2\u00a0 It also provides the precise pressure to allow phase change interface material to be used to it’s best advantage with a heat sink.\u00c2\u00a0 You can learn more about superGRIP by visiting ATS’s Slideshare Channel<\/a> or by visiting ATS superGRIP Web Site<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
