2016 Annual Summary
I graduate in 15 years in June, early July to get a driver's license in mid-July came to Shenzhen to get the first job in radio frequency products development. The company first came to feel that everything is fresh, but less than four months got tired of the job, so the application submitted his resignation in November. After the resignation, I did not continue to look for work, choosing instead to stay in Shenzhen to continue learning, adhere to a month after the body and mind really could not carry, had to choose to go home. 15 December to 16 February, I was at home for their first job had a profound reflection, as follows:
a lack of clear objectives when (1) graduate school, learning is not enough effort has led to looking for work passivity;
(2) the wrong direction, he did not study for RF, but cock into this industry;
(3) work, there is a serious contradiction to their line of work, the loss of enthusiasm;
on March 16, I re-start, find a second job in Guangzhou, in communications equipment development. After a three-month internship, I successfully completed a positive reply to the end of June. During the internship, the main task is familiar with the department of product characteristics and test methods. I June to September period, mainly responsible for the development of PD end POE switches, has been tried on three options, but only the first program debugging success. I October to December, the revision work is mainly responsible for the termination card, autoCAD initially learned to use during the project, and the successful design of CAD drawing card terminal apron and custom audio cable. By exercising the above items, I have ideas for product development and process more profound experience, as follows:
(1) the beginning of the project design, to fully investigate each chip versatility and procurement cycle for the popular and procurement cycle long chips, the need to find alternatives;
(2) when designing circuit PCB, first of all to observe strict quasi-company design specifications, and secondly, as many add debug point interfaces need to specify the property name;
(3) in the material single link, need to be checked, to prevent or leave out the wrong;
(4) in the sample application areas, needs time to follow up the progress, maintain close contact with the requisitioning office;
(5) in upgrading and transformation circuit, we need to be classified for each version, and a good record of each version changes the situation, BOM table to be updated to keep pace;
(6) before the product is small series production, to make full testing, identify and solve problems that may arise.
Outside of work, I am also following the direction of a preliminary study:
(1) PCB design of DDR2
candidates through a company in Shenzhen before the hardware engineers, developers experience when asked whether DDR2 telephone consultation, because there is no contact so missed the interview. Although the missed opportunity to interview, but I firmly believe that reserve in advance DDR-related design knowledge, we will certainly have its uses. I have read the written by Linchao Wen teacher "Altium Designer combat Raiders with high-speed PCB design", in conjunction with operation of the video CD, independently of DDR2 PCB design.
(2) Cadence Allegro circuit design
reasons Cadence's study has two, one will AD many people, but will Cadence relatively few people, and large companies generally use Cadence as the main PCB design tool; two as Cadence PCB design industry's high-end software, it has more design advantages. Up to now, I've been watching the fight due to doctor explain "Cadence video tutorial," the top 40 say, are adept at using Capture CIS schematic drawing, using a variety of design Pad_Designer pad and use PCB Editor design package, but PCB design still in the introductory phase.
(3) embedded development
due to the need of the next project, need to have some understanding of embedded development. Currently, based on Ubuntu8.10, we completed the build tools chain of Broadcom switches.
16 years, I showed a lot of shortcomings, mainly reflected in:
(1) energy at night to work overtime to keep up, often drowsy
main reasons: too frequent use of mobile phones, as well as the lack of an appropriate amount of physical exercise.
(2) At work, the lack of long-term planning, short-term lack of efficiency
main reasons: there is no plan to develop detailed short and long term, there is no breakdown priorities at work.
(3) the character is not mature enough;
adhere to self-examination, a problem first from their own.
(4) weak self-control;
this too slowly overcome.
17 years of my training habits direction as follows:
(1) regular rest and exercise;
(2) adhere to the study, writing blog;
(3) will be a good plan, persevere;
(4) keep reading, to cultivate an interest.
