The [WEP/Atten/Yihua//Wylie/etc] 858D has served me well for several years now. The handle is chunkier since it has a small squirrel cage blower instead of a remote aquarium-style air pump, but it’s a lot cheaper and has fewer parts to break. It also functions well as an intermediate tool between a hair dryer and a heat gun, which is nice for more delicate tasks like heat shrink tubing/Monokote for RC planes/welding & bending small plastic parts/making tiny servings of crème brûlée/etc.
As with all no-name equipment from China, be sure to check the wiring: http://www.eevblog.com/forum/chat/deadly-wiring-fault-atten-858d-hot-air-rework-station/ If you prefer an iron and only have a few large ICs to remove, there’s also the option of low melting point solder: http://www.chipquik.com/store/ http://www.zeph.com/lowmelt.htm Tools for grabbing components: - good quality tweezers - a manual hand pump (www.ebay.com/itm/131206538767) only useful as a source for pickup tips when connected to an aquarium pump for a DIY tool - the fantastic but expensive Hakko 394 http://www.amazon.com/Hakko-394-01-Vacuum-Pick-Up-Safe/dp/B009SCKYV6 Side note: I’m never giving up my classic Hakko 936 — you can’t stack anything on the new Hakko soldering stations because they’re rounded on top! ---------------- [email protected] (Email/XMPP) https://kirkovsky.com OTR Fingerprint: 0DC94FB7 CF0F6989 E2746A37 0EADCF54 00145E35 Key fingerprint: 4328CFD67B46A8FB32270F4F0CE4A0B83F3FC81F Public Key: https://kirkovsky.com/pubkey Public Key (PKA): `gpg --auto-key-locate pka -ea -r [email protected]` Public Key (Github): https://gist.github.com/pkirkovsky/01071907297b34829249 On Mar 11, 2015, at 10:29 AM, David Madden <[email protected]> wrote: > On 3/11/15 10:17 AM, Philip Odom wrote: >> Second on the Metcal stuff, if you want to spend the money.
